Razer Viper Ultimate Review

Over the course of the past few months we've seen a number of really exciting gaming mice being dropped on the market, and it seems like the race to innovate and push boundaries is fiercer now than ever before. A while ago Razer released the Viper: a well-received lightweight gaming mouse that perhaps went a bit unnoticed in a sea of other (lightweight) releases.

The same can't be said for the Viper Ultimate, however. From the moment it was first leaked, enthusiasts started licking their lips at the possibility of a lightweight wireless gaming mouse to contend with the ever-popular Logitech G Pro Wireless. A short while ago the Razer Viper Ultimate was announced and subsequently released. With a brand new sensor, optical switches, a bunch of interesting features (including the fact that it's wireless) and a weight of just 74 grams Razer definitely hasn't been making any compromises, so it's no surprise that a lot of gamers are giddy with excitement about this one.

Is the Viper Ultimate all that it promises to be? Could it be the ultimate gaming mouse? Read our reviewer's report to find out.

"The wireless speed on this mouse is really fast and it doesn't feel like I am playing on wireless. The sensor is very accurate too which is important when you need to kill your opponents fast."Taco, CS:GO pro, on Razer's website
Razer Viper Ultimate Review

Razer Viper Ultimate - First Impressions

There is a lot to unpack about this mouse, and I mean that literally as well as figuratively. The device itself looks very sleek and 'stealthy,' with the little cutout between the shell and the main buttons being a noticeable design element. The RGB factor comes in the form of a programmable Razer logo at the back of the mouse. What's cool here is that, if you turn that lighting zone off, the logo becomes almost invisible.

The Viper Ultimate comes with a charging cable that you can plug straight into the mouse so that you can keep playing while you're charging the mouse, but I can't imagine why anyone would want to do that since you also get an amazing charging dock. This dock doubles as a receiver extender: there's room for the USB dongle to be plugged in on the top so that your receiver is right next to your pad at all times. It's a really cool way to combine two actually useful functions, and even the RGB (it has a strip all along the bottom of the unit) serves a purpose, as you can program it to display the current battery level.

The Viper Ultimate is light. On my scale it weighs in at 74 grams, which is light even for a wired mouse so it's really impressive to see this in a wireless product.

It's a medium sized (though pretty long feeling) ambidextrous design with side buttons on both sides, meaning that it can be enjoyed fully by lefties as well as righties.

On the bottom you'll find a tiny hatch that stores the USB receiver along with an on/off switch and a DPI selector button (and indicator LED) and then also the two connector elements for the charging dock.

Razer Viper Ultimate Review Packaging


Inside the box you get the mouse along with a charging cable and the aforementioned mouse dock.

There's also the usual documentation as well as a printed note from Razer's CEO thanking you for purchasing their stuff and a pretty generous amount of Razer stickers.

What I like here is the fact that the box opens from the side via a magnet system. This makes it really easy to repack the mouse (and extras) in case you're going to a LAN or something to game.

Shape and finish

The Razer Viper (Ultimate) is an ambidextrous mouse with very little curvature anywhere. It does flare out a tiny bit at the back but this isn't substantial in any way so I don't think this could get in the way of anyone, regardless of grip style. It's also pretty long and flat, with a gradual curve at the back as opposed to a sudden one, so if you like to have a filled palm this is something to note. Overall this is a pretty safe shape, and if you like this sort of flat ambidextrous design (think Zowie FK or Glorious Model O) it's hard to imagine that there's anything to dislike here.

The coating consists of two parts; you've got matte black on top of the shell and the main buttons, and then on the sides you'll find textured rubber elements. Those of you who read my reviews with any sort of regularity will know that I love rubber side grips so I adore the way this mouse feels in my hands. The combination of the nice shape (for me personally; always remember that shape is subjective) and the rubber sides gives me a great grip under all circumstances, and the non-rubberized parts of the mouse feel great too.

Even after a CS:GO marathon spanning just over eight hours the mouse looked as if it was just taken out of the box. As someone who gets sweaty hands pretty easily when gaming I don't like it when mice have a tendency to pick up skin oils, and the Viper Ultimate handles all of that like a dream.

Both side buttons are nicely placed for me, but I do have to say that I clicked the side buttons on the right side by accident once or twice during my testing. This isn't a big deal, especially since there's not a lot of travel to them and I deactivated them so my erroneous clicking was of no consequence but I thought I'd mention it regardless in case you're someone who's sensitive to this sort of thing.

On the bottom there are four medium sized feet along with a ring that surrounds the sensor, all made out of pure PTFE. These skates feel great, providing a really smooth and consistent glide straight out of the box. After the 'lightweight and paracord cable revolution' of the past months it seems like companies are now also shifting their focus towards the feet, and that's lovely to see.

Buttons and scroll wheel

The release of the original Razer Viper also meant that Razer's optical switches saw the light of day for the first time. Compared to a traditional mouse switch, these don't need physical contact in order to send a signal to the PC and that, according to Razer, results in a response time of 0.2 milliseconds. I say 'according to Razer' because I obviously don't have the equipment to do tests that require this amount of precision, but what I can test is how it all feels and performs.

The main clicks on the Viper Ultimate definitely do feel less crispy and snappy than what you get with (quality) mechanical switches so if you're really sensitive to how your clicks feel this is something to consider. I can't really say that I notice the fact that they're supposed to actuate faster than mechanical switches (it's not like there's a noticeable delay with regular switches anyway) but I never had any issues with accidental or unintended clicks, and the fact that these switches last a lot longer than regular mechanical ones (70 million clicks versus 50 million) and make debouncing delay obsolete makes them a hit in my eyes.

I don't particularly need extremely snappy clicks so I'd take these more durable and faster switches over traditional ones any time of the year, but don't come away from this thinking that your ingame reaction times will be three times faster after getting this mouse or anything like that. It's a great innovation, and the added durability along with the fact that these switches eliminate the possibility of accidental double clicking makes them worthwhile, but in actual gaming situations you don't really feel a difference between this and other top tier gaming mice.

What you do definitely feel is how nicely they've implemented the buttons; there's no sideways movement and while there is a tiny bit of post click travel on my unit it's barely enough to even mention, so as a whole I really love the overall clicking experience with this mouse. The side buttons follow right along, too. They actuate with a pleasing click and there's barely any travel to speak of there as well.

Something that I'm a bit less excited by is the scroll wheel. It's just not sticking out of the shell enough in my opinion, and I also feel like it's a bit too rigid. I don't know if this is something that's only on my copy but scrolling down feels notably easier than scrolling up, making for a bit of an inconsistent feeling. It does register everything just fine and it's almost perfectly silent so it's definitely not a bad wheel, it just doesn't suit my personal tastes and I'm not a fan of the inconsistency between scrolling up and down.

Quality and cable

Shaking the vertically reveals a little bit of scroll wheel rattle, but other than that I can't find any flaws on this front. The shell is very sturdy all throughout and there's absolutely no way to accidentally actuate a (side)button by applying pressure on the shell so the build quality is up to scratch as far as I'm concerned.

In lieu of a cable, the Viper Ultimate sends signals to your PC through Razer's HyperSpeed Wireless. This does exactly what you'd expect it to do, but more on that in the next section. Wireless products, as we all know, need power to perform. This mouse comes with a rechargeable battery that can provide you with enough juice to game for 70 consecutive hours. Should you by any chance go on a medically miraculous 70-hour binge or you forget to charge your mouse you can always plug in the included charging cable and game while the mouse is charging up.

This cable securely connects to the device in such a way that it looks and feels as if it's a wired mouse and I'm honestly impressed by how nice the cable is. It's not quite paracord style (it's a bit too thick and rigid for that) but it's definitely nice enough to use in a pinch for gaming. With the convenience of the charging dock you shouldn't ever be in a situation where you need to use the cable, but it's still nice to know that you won't be slinging around a fire hose in case you have to.

Performance and sensor

Razer has really been throwing the kitchen sink at this mouse; not only did they make it wireless and included their new optical switches, they've also equipped the Viper Ultimate with a brand new sensor. The Razer Focus+ is the result of a collaboration with industry standard sensor manufacturers Pixart, and boy does it pack a punch. This one goes up to 20000 DPI, but aside from this fairly useless increase in sensitivity it also has a number of really nice features.

My personal favorite function is the Asymetric Cut-Off. With this you can not only customize the LOD but you can also set at what distance the mouse should resume tracking after you've picked it up. This doesn't sound super useful for people with a high or medium sensitivity but if you pick up your mouse a lot due to your low sens this is a really nice feature to have. There's also Smart Tracking, where you have to run your mouse over your entire playing surface after which the software (Razer's Synapse) will calculate the ideal LOD.

The sensor itself is, as you would expect from a top tier gaming mouse, flawless. It tracks every move with pixel perfect precision and my testing found no evidence of smoothing, acceleration, angle snapping, or any other tomfoolery. It feels extremely responsive ingame and with its ability to keep tracking as long as your hand moves under 16 meters in one second it's every bit as reliable as you want it to be for high performance gaming.

All of this would be moot if the wireless connection packed its bags and left every couple of minutes but Razer's HyperSpeed Wireless performs every bit as good as their wired mice. There's no perceptible latency at all and the connection didn't drop even once during my testing. Razer's done an outstanding job here, both with this sensor and with the wireless tech.

You can adjust the lighting and create macros and all of that good stuff in Razer's software but the Viper Ultimate also has onboard memory for up to 5 profiles for that complete plug and play feeling.

Overall the Viper Ultimate is a joy to use, but I also have to give a special shout-out to the dock here. Setting the mouse down on the dock whenever you're not going to be behind your PC for a while is very easy and satisfying and it ensures a constantly charged battery. On top of looking pretty damn sweet with the RGB (I know this isn't of importance for a performance product at all) its double function as a charging dock and a neat place to store the receiver right next to your pad makes it way more than a silly added gimmick.

This mouse has a pretty safe shape but it is rather long and flat so this, in theory, isn't ideal for palm grippers or for people who like a filled palm in general.

If your hands are on the smaller side I'd try and get those same hands on a real life model (the Viper wired is the exact same) before purchasing, because this isn't exactly the smallest mouse on the market.

For anyone else this should be a good one; due to the fact that there are no awkward curves or grooves it houses a very large variety of grips with ease and there's plenty of room everywhere on this mouse to ensure a comfy hold no matter how you like to place your fingers.

Razer Viper Ultimate Review Backside

Conclusion & Recommendation

This is one of the easiest recommendations I've made in my career. Razer might have (had?) a bit of a reputation for releasing overly marketed 'form over function' products in some parts of the community but this release proves that they absolutely know how to make a top tier product.

The fact that this is a wireless mouse with a lag-free connection and flawless sensor, complete a rechargeable battery (with a life of around 70 hours) at a mere 74 grams is impressive enough on its own but Razer has managed to get over the proverbial bar and then set it even higher with a number of interesting upgrades.

The optical switches may not feel as clicky and crispy as their mechanical counterparts but they do eliminate accidental double clicking entirely and you also get the added durability and speed, even though that last aspect isn't actually noticeable ingame in my opinion. The sensor doesn't only do the usual (useless) 'we've raised the DPI' trick but also gives you actually handy features such as Asymetric Cut-Off. Whether or not these things apply to you as useful will depend on your playing style and preferences but it's really nice to see how Razer tries to push the boundaries here.

Even if you totally ignore the new features that Razer has added you've got one of the best gaming mice in recent years here; the only thing I can actively criticize is the scroll wheel and the fact that the optical switches aren't as snappy as mechanical ones.

With a great shape, low weight, flawless sensor, great stock feet, a perfect wireless connection, and a number of interesting features this is one of the best gaming mice you can buy right now and without a doubt one of my personal favorites.

Hello, I am looking for a gaming mouse and I am confused for which to choose. I have in my mind the Razer Viper Ultimate or the Logitech G Pro X Superlight.
I have small hands and claw grip.
Which would you recommend me?


My hand-size is 13×9, Do you have any recommendations for playing fps ? (wireless is better :))

ProSettings | Max

It depends on your grip. If it’s palm you might take a look at the G Pro Wireless, for example, but I wouldn’t recommend that if you’re a claw or fingertip gripper with that hand size. Wireless options are still pretty limited at this point in time, but you can also look at the Glorious Model O Wireless (although I still haven’t gotten to test that one yet so I can’t speak of the quality) and if you don’t mind wired there’s the Viper Mini if you like the shape of the regular Viper but you’re afraid it might be too big.


Ok, so I’ve been trying to figure out what mouse I should get. I use claw grip and my hands are medium 20cm and I am mostly stuck between the Razer Viper Ultimate or the G Pro Wireless yet I am open for suggestions. The game I mainly play is Overwatch. I am more of a low sense player.

ProSettings | Max

If you like a bit of a hump towards the back that kind of fills up your palm you should go for the GPW between those two. If you like it a bit flatter then the VPU seems like a good bet. It’s worth noting however that an updated version of the G Pro Wireless is going to come out soon (™); we’ve been seeing leaks upon leaks and a lot of teasers so I assume that’s not very far off.


when liking smaller lighter mice (with lower sens), do you think it’s a good idea to switch from s2 to viper ultimate? i know viper is a bit bigger but lighter. do you feel the size and or weight difference between s2 and viper?
[for more reference: my hand cramped on an ultra light 2, old wired GPro felt weird – too flat, rival 300 and remastered mx518 were too big, xm1 was fine]
thanks for all the help you provide to everyone <33

ProSettings | Max

I’d say that the shape difference between the S2 and the VPU is pretty significant, much more so than the weight difference, at least for me. This is personal (it might be different for you) but I don’t really perform any better in aim trainer scenarios with ultralight mice over ‘regular weight’ (<80 grams) mice myself and I don’t really notice any major performance differences ingame either but I do have to say that I play mostly tac shooters. So to answer your weight question: I do notice it, but it doesn’t really matter for me personally.

The shape is something different: the VPU is a very flat and neutral feeling mouse with almost no hump (think Zowie FK) and as such it’s got a very different hand feeling than the shorter feeling and humpier S2. If the S2 fits you nicely I wouldn’t say that the VPU is necessarily too big or something, it’s just very different in my opinion.

So to answer your question: it’s very personal. You might like the VPU a lot better than the S2 but if you’re comfortable on the S2 I wouldn’t really switch if I were you, unless you’re looking for a flatter profile mouse with a larger hand feeling.

Let me know if you don’t like the S2 all that much and want to try something different or if you have any more questions: always happy to help!


so you mean you can not compare the size because of the shape being so different :,(
unluckily i always want to try something different and new.
i have one more question about the wheel of the VPU; in the review you said "too rigid" so you precisely feel every step / tick just like on the zowie ones?


got my VPU and is very good. for me shape is not too different to s2 and i think i will be able to aim a little bit better. my main for now <3


Which is better for sweaty hands? I mean between GPW and RVP, I have ROG Gladius II and I don’t like it when I get sweaty in this mice.

ProSettings | Max

I like the coating of the VPU better and it has rubber sides which could be viewed as better for sweaty hands so I’d say the VPU. I have quite sweaty hands myself when gaming though and I have no problem using either, for what it’s worth.


I bought the gpro wireless recently and I use 800 dpi and 5.2 x y on fn. What mousepad would you recommend?

ProSettings | Max

That honestly depends. Some people like a controlling mousepad while others love the feeling of speed. If you want as much speed as possible you could take a look at the Endgame Gear MPC mousepads, or the Fnatic DASH. For control you could look at the Zowie G-SR. Something in between would be a Corsair MM350, for example.

In short: there are so many differences between pads (and the preferences of each individual) that it’s impossible to just straight up recommend a pad like that. We do have reviews on almost all popular mousepads so feel free to check those out!

If you have any more questions do let me know, always happy to help!

Wow, for guys with smaller hands, this is soooooo much better than the Logitech Pro wireless. That is a good mouse but I can’t really tell because of that huge bump in my palm. This is closer to the mousepad and is very accurate and fast. Much better than the Pro…. I think… I’ll test em side by side when I get home…. accurate and fast and feels great under my hand. I wear a cadet small or medium golf glove. I like rechargeable mice but the Logitech charging matt is a no brainer. Don’t even have to put it on a dock. Perfect. Charging that is…. I think this mouse has better response and accuracy. ONLY NEGATIVE FOR ME IS I’M ON AN APPLE MACBOOK PRO… I can’t configure any of the lights or settings until I start building my ITX gaming PC with Windows 10 later next year. If you have medium to small hands, this is a must!

ProSettings | Max

It really is a great mouse indeed! Good to hear that you’ve been able to find one that fits you like a glove, haha!


Im deciding to get either a gpw or a viper ultimate but there one thing that i need to know, which is that the side buttons on the viper. It looks flushed into the mouse and looks like its harder to press, whats your opinion on the side buttons.

ProSettings | Max

I honestly have no problems with the side buttons of the Viper at all. I’ve used the Viper Ultimate as my main for a couple of months and I’m pretty sensitive to subpar side buttons and I had no issues there. On my copy at least they’re easy to press and don’t travel into the shell at all. Between the GPW and the Viper Ultimate I’d say that the side buttons are pretty much equal when it comes to quality.

Jeremy goh

do you feel any difference in the sensor between the g pro wireless and the viper ultimate? and does the optical switch make a difference? also can you tell the weight difference in the g pro wireless and viper ultimate?

ProSettings | Max

Realistically (i.e. ingame) I can’t really feel a difference. Both are flawless sensors that did their job perfectly. The Viper’s sensor is technically the superior one though, thanks to a number of improvements and extra features.
The Optical switches are more durable than the mechanical ones in the GPW, and due to the way they’re constructed there’s no chance of encountering the famous double clicking issue so on paper the optical switches are much better but you do have to live with them being quite mushy. Newer mice with the Razer opticals have gotten crispier but the Viper Ultimate was one of the first mice to use these new switches so it’s pretty spongy all things considered.
I definitely feel that the Viper Ultimate is a bit lighter than the G Pro Wireless but that’ll vary from person to person and it’s not like the GPW feels unwieldy in any way.


What mouse can you recommend to me for fn and val? I have 18.5cm x 9.7cm hands and use fingertip grip and use claw when my hands get tired. Thank you.

ProSettings | Max

For fingertip with that hand size you might want to look at the G305 (or any of its wired variants such as the G Pro Gaming Mouse) or perhaps the Endgame Gear XM1. The Zowie S2 might also be worth considering, as well as the Razer Viper Mini. These are four options: if you have any questions about any of them feel free to let me know!


Should I go with the Razer Viper Ultimate or Logitech G Pro Wireless in your opinion?

ProSettings | Max

It really depends. The Viper has inferior clicks (in my opinion: they’re much mushier since they were one of the first iterations of Razer’s new clicks) but it does technically have the better sensor. In reality though I think it’s the shape that will be the decider for most people. The Viper is much flatter while the GPW is more filling so I would decide depending on what you like most since both are absolutely fantastic mice with very little objective downsides.


which mouse pad would be the best for fortnite with that mouse

ProSettings | Max

This completely depends on your preferences, but if you want to get some inspiration you can always look at our Fortnite mouse and mousepad guides!


what response time is this mouse? is it equal to the model o and final mouse?

ProSettings | Max

Yup, Razer’s wireless is on par with wired mice like the Model O and Finalmouse mice!


This mouse can be used professionally in championships … For fortnite ? … And which one do you recommend … between G PRO WIRELESS or RAZER VIPER ULTIMATE

ProSettings | Max

Yes, it has a flawless sensor and lossless connection so this can be used at the highest levels of gaming. Which of the two you like depends on your preferences; the Viper Ultimate is much flatter and longer feeling than the GPW, so if you want a fuller palm feeling you could consider the GPW but if you like them flat the Viper Ultimate can be a good choice. Both are flawless though so it really comes down to the shape, aside from the fact that the Viper Ultimate has mushier clicks than the GPW.


I have the razer viper ultimate, love it. Came from a zowie fk2. The viper fits perfectly in my hand, very comfortable. Love the battery life, barely have to charge this thing.

ProSettings | Max

It’s a super great mouse indeed! Would be almost perfect if they had made the clicks a bit more crispy in my opinion. But I do agree with you: it’s my daily driver as well.


I’ve used the model o- for a few months now and I’ve been thinking of going wireless. I forgot my hand measurements but it fits perfectly with the model o-. Do you think there will be a big difference with the Viper shape and size?

ProSettings | Max

The Viper Ultimate is a bigger mouse but the difference isn’t absolutely massive and the shape has pretty much the same ‘design philosophy’ (flat and ‘long feeling’) so I don’t think that you’ll have too much trouble adjusting unless you really want a small feeling mouse and you don’t think you’d be happy with a mouse that’s larger than the O-.

I just recently read confirmation by Razer that a Viper Mini Ultimate is not in the works, so unfortunately that’s not going to be released any time soon (or ever) otherwise I would tell you to perhaps wait for that.

But in short: if you can stomach a bigger mouse I don’t think it’s going to be a massive adjustment.


I`m currently using Logitech G403 Prodigy (wired). I’m thinking of switching to a wireless mouse. Which can you recommend?

ProSettings | Max

If you love the G403’s shape then the G703 is an easy recommendation since that’s the wireless version of the G403. One downside of that mouse is that it’s rather heavy. You can always lower the weight a bit by doing a couple of (relatively easy) mods but I understand that tinkering with a brand new and pretty expensive gaming mouse isn’t something that most people want to do.

If you want to venture on to a different shape then the G Pro Wireless is a good bit if you want to have a similar ‘full’ feeling mouse; the shape of the GPW is different than that of the G403 of course but you do get a rather filling hump. The Viper Ultimate is another insanely good wireless mouse but it is noticeably flatter and longer feeling than the G403 so you might have to take some time getting adjusted to that one.

Hope this helps, but if you have any more questions feel free to let me know!


which one you recommend razer viper or viper ultimate or viper mini?
my hand size is 18.5cm height and 9.4cm width.
basically i have claw and claw palm grip

ProSettings | Max

With that size and grip I’d recommend the regular Vipers, I think that the Mini will be too small to have any significant part of your palm resting on it, even if you’re not going for a full on palm grip. As far as deciding between the two I’d say it comes down to what you prefer. I love the wireless aspect of the VPU so I’d go for the Ultimate, but if you don’t really care so much you can go for the regular Viper.

The Ultimate technically has a better sensor but the sensor in the regular Viper is a flawless sensor as well and unless you’re gaming at 20k DPI (you shouldn’t) you’re not going to notice any ingame difference. Aside from that though, if money isn’t really an issue, I’d go for the Ultimate.


Which one would you recommend? The Razer Viper Ultimate or Logitech g pro?

ProSettings | Max

I get this question a lot, and it’s not weird to see why. Both mice are pretty similar, so much so that I can’t really give you an answer here. The Viper Ultimate has a flatter profile and feels longer in the hand while the GPW is shorter and more filling feeling. Aside from the shape both mice are extremely close though. I do like the clicks on the GPW better; the Viper Ultimate has an early iteration of Razer’s optical mouse switches and those are very mushy when compared to later versions.

I’m sorry that I can’t be of more help but the mice both perform absolutely flawlessly so the shape will be the deciding factor and that’s a personal thing. If you can give me your hand size and preferred grip I might be able to give some more in-depth opinions but in the end it really comes down to what you prefer here.


What mouse for a hand 18.5cm / 10.5cm do u recomend this one, or MM711 coolermaster ? The cable inst a problem for me, I only want a good mouse with lightweights and good sensor…

ProSettings | Max

It depends on your grip, but I haven’t personally tested the Coolermaster so I can’t really recommend that one. That said, the MM711 is pretty small so perhaps the Viper is better for your hand size, in general (since everyone is different).


Im a fingertip grip guy and i have a razer viper wired .. i wanna buy a wireless one , you think logitech g pro wireless is good for fingertip? I got a medium to large hand … pls help me !!

ProSettings | Max

It depends; if your hand is big enough for the mouse (this depends on personal preferences) then theoretically the Viper would be best since it’s flatter. I’d say if you like the shape of the Viper wired you should go for the Viper Ultimate if you want to go wireless, but if you want a bit more volume then the GPW is where you should look.


They are not as annoying as the ones from Zowie because this mouse has more grip width and it’s harder to press the buttons, that’s my experience with it by palm gripping it.

ProSettings | Max

Thank you for sharing your thoughts!


Anyone using the viper ultimate on a fingertip grip? I think the buttons on the right side are a bit annoying.

ProSettings | Max

The way I use it the side buttons don’t really get in my way (the only contact point on the right side of the mouse is the tip of my ring finger towards the front with my grip) but I can definitely see how the side buttons can be annoying if you’re constantly gripping there. Perhaps it could be an idea for Razer to make these modular with the next iteration of this mouse.


I am using zowie S1 now, and I am thinking about the question,GPW or ciper Ultimate.What’s your suggestions?

ProSettings | Max

It really depends. The Viper is a lot flatter than the GPW, but other than that both are at the top of my personal list as far as gaming mice go. The real differences are the shape and the clicks (which are better on the GPW) in my opinion, but things like the feet (better on Viper) or weight or maybe even the inclusion of the mouse dock can be differentiators depending on your preferences. You can’t really go wrong with either mouse, but shortly said: if you like a flatter design go for the Viper, if you like a more full design go for the GPW is what I would say.


How is this mouse not in your top 5 mice guys? it’s the greatest on market rn

ProSettings | Max

That list is based on what the pros are using, but we might add it to our own picks when we update the list (which should be soon, by the way) since it is indeed a fantastic mouse.


I bought the razer viper ultimate last week after reading your article and I am really satisfied with the mouse. It’s a great mouse and your article is really accurate
Thanks for all the information

ProSettings | Max

Hey, thanks for the kind words! Always happy to hear these things, and glad you’re liking the mouse!


What sense should I play on with the Razer viper ultimate ?
I love the mouse .
And awesome content and answering all the questions .
Well done

ProSettings | Max

That really depends on your personal preferences. You can always take a look at our settings guides to get an idea of what sensitivity the pros are using. While I’d never advise anyone to blindly copy a pro just because they’re pro it is a good starting point to use if you’re just getting into gaming.


Great Content. Review is amazing. Keep Up the good work.

ProSettings | Max

Thank you for the kind words!


Hello ProSettings. I would like to ask if you recommend me switching to the Viper Ultimate from Zowie S2… Does it have similar shape? I’m using claw grip but not that aggresive.. I’m still thinking about it and I just can’t decide.. =D Thanks in advance!

ProSettings | Max

It’s not really a similar shape in my experience. Both are ambidextrous mice but the feeling in your hand is quite a bit different, with the Viper feeling a bit lankier and flatter. As far as other characteristics go it kind of depends on what you prefer; the Viper Ultimate obviously has no cable, while the S2 has slightly better clicks.


You mention length is: 12.93 cm / 5.09 in
real length is 12.45cm | 4.9 inches

It depends on where exactly you’re measuring. On Razer’s official site it says 12.68 cm, for example. I use a digital caliper to measure the mice I review, but even so these things can have variations between them. These measurements are really just to indicate what the size is approximately.

Hi, do u think my hand suit with the razer viper?
My hand is 17cm x 9.5cm.

ProSettings | Max

Depending on your grip that could work, though it might be a little long.


Do you prefer the finalmouse ultra light 2 or the Razer viper ultimate? And also do the side buttons on the right side of the Razer viper ultimate a bother for gaming?

ProSettings | Max

I haven’t tested an Ultralight 2 in depth so I can’t really say. I will say that the side buttons on the Viper aren’t a bother for me at all, but depending on how you hold the mouse it could be that you feel them clicking every once in a while. How much this bothers you will depend on your preferences of course.


Will viper work for my small hands (18cmx9cm)?

ProSettings | Max

It depends on your grip and personal preferences to be honest; if you like larger feeling mice it could be okay but it’s definitely cutting it close.


What mouse would u reccomend for 19×10.5 cm hands, claw/fingertip grip?

ProSettings | Max

The Viper would be a good one for that, as well as the Zowie S series, or the Glorious Model O. The Endgame Gear XM1 is also an option if you like smaller feeling mice. There’s also the Logitech G Pro Wireless if you like a bit more of a ‘fuller feeling’ mouse. There are honestly plenty of options, but I hope this has helped you along the way a bit.


I need a mouse mat so.Suggest something not very expensive to me.

ProSettings | Max

A good ‘starter pad’ that’s very widely available and pretty friendly on the wallet is the SteelSeries QcK line. You can of course always take a look at our mousepad guide here: https://prosettings.net/best-gaming-mousepad/


I like the DeathAdder Elite Shape but its feels a bit too big and too heavy .
Should I change to this mouse?
I’m also a fun of bit big backs on the mouse to rest my hands in between gaming

ProSettings | Max

If you like a pronounced backside the Viper Ultimate isn’t for you. Perhaps take a look at the Zowie EC, G-Wolves Skoll, Glorious Model D, or Xtrfy M4 for a lighter and smaller mouse with a similar feeling to the DA Elite.


Currently I don’t see a single pro listed as using this mouse.. there is one mouse rocking the top of every pro-chart today and that is the g pro wireless. Is this only down to the Viper Ultimate being too new? Is it expected that lots of pro’s will turn over to the Viper Ultimate?

ProSettings | Max

Well, most of the pros that we analyze (except for Fortnite pros, but they seem to be more into the ultra lightweight thing) don’t change their gear all THAT often. A lot of CSGO pros, for example, are still on EC2-A mice because they feel comfortable using them. That said: it always takes a while before a product really breaks through.

Once some pros start using the Viper Ultimate there might be some sort of snowball effect (where their teammates ask to hold it and maybe switch themselves and so on) or it might not happen at all; we can’t know that for sure.

Also important to note is that the Viper Ultimate came out pretty late in the year. Lots of pro scenes have a kind of break during the holiday period so there aren’t as many opportunities (such as tournaments) to spot the gear of new players so we might see the mouse pop up more often as the pro gaming scene gets back into gear.

Again: this is all theorycrafting by me, it could also be that most pros stick to what they’re using and leave the Viper Ultimate to be what it is. It’s very hard to predict these kinds of trends.


Razer viper ultimate or g pro wireless

I hope you don’t mind me copy pasting a previous response. It’s a very fair question but one that gets asked a lot. I feel like the shape is the major factor that will decide this battle for most people. One mouse might be slightly better than the other (better clicks on GPW, better stock feet on Viper, …) but the differences, in my opinion, aren’t so massive as to really firmly and objectively sway the decision one way or another. I’d say if you’re considering these mice to really factor in the shape; the Viper is much flatter and longer feeling than the Viper Ultimate, so if you prefer a more filled feeling for your hands then the GPW could be the one to go for.


Hm, though which is better of this and Logitech Pro Wireless. All even?

I’ll buy the viper for claw grip but what is the best mousepad for r6s

ProSettings | Max

As luck would have it we have just been working on a Rainbow Six Siege mousepad guide! The SteelSeries QcK+ came out as the winner of that one, but of course these things greatly depend on personal preferences so you might not like that pad as much as the pros do.


Hi prosettings, I plan to change mice and I hesitate between the viper and the g pro. My hand is 19cm by 10 cm and I play claw grip. Can you please advise me ? Thank you.

ProSettings | Max

Depends on whether you prefer a filled palm or not. The G Pro Wireless has a bit of a hump to support your palm whereas the Viper Ultimate is mostly flat. There are other differences obviously but since both mice are top performers with little to no objective downsides it’s best to compare shapes in my opinion.


Is this size and shape comparable to the Air58?

ProSettings | Max

Not really in my opinion, apart from the fact that both are ambidextrously shaped.



ProSettings | Max

I haven’t tested the Air58 myself, but since the Viper is commonly available and the Air58 isn’t I’d wholeheartedly recommend the Viper.

Josh Exton

is it worth getting over the regular viper

ProSettings | Max

I haven’t fully tested the regular Viper, but I do think that the improvements are worth it. The feet and cable (or rather; the lack thereof) alone are substantial upgrades.

Ryan J

Yes, better sensor, better clicks, no cable.


what is your daily driver mouse ?

ProSettings | Max

We’re a team of multiple people but mine (the reviewer) is the Razer Viper Ultimate at this point. I’ve used the G Pro Wireless for about a year as a daily driver before that.


Thinking of buying this. For you personally, what mouse has the most comfortable shape?

ProSettings | Max

The EC and S series by Zowie immediately come to mind when I’m asked about comfortable shapes. This is obviously subjective but for me Zowie are the ones to beat if it comes to shapes.


This and the Zygen NP01


Which one would you recommend? The Razer Viper Ultimate, Model O or Model O-?
My hands are 20cm by 10cm and I use claw grip.

ProSettings | Max

Personally I would recommend the Viper Ultimate; having no cable is always better than having one, even if it’s a really good one. Of course it’s easy for me to say this since I don’t have to think about budgetary restrictions but the Viper Ultimate really is an extremely good gaming mouse in my opinion.

The shapes are extremely close so it’s really just a matter of looking at the features; do you prefer wireless or is that not a concern for you, do you like holes in your mouse, …
