Logitech G305 Review

When Logitech dropped the G Pro almost two years ago now it was almost universally agreed that it was a massive hit, and even though shape, weight of clicks, and all of that is subjective there was one aspect of the mouse that everyone agreed on: the cable was pretty bad. The G Pro came with a stiff, braided cable, which just had no place on a mouse that was, for all intents and purposes, aimed at the hardcore gaming market.

'Alright,' Logitech must've thought, 'if you hate the cable so much we'll just remove it entirely' and that is just what they did with their newest release. Logitech took the shape of the G Pro, slapped their own HERO sensor in it, equipped it with their LIGHTSPEED technology (my caps lock key isn't broken, the official names of these technologies are in all caps) and released what is logically called the Logitech... G305.

Odd Logitech naming schemes aside; we now have a fully wireless (and still lightweight) Logitech G Pro. Is the G305 worth your hard earned money? Is the wireless experience really that liberating? Read our review to find the answers to all of your questions.

Note: The G305 is called 'G304' in some parts of the world. It's the exact same mouse with the exact same specs though.

Logitech G305 - Initial Impressions

The G305 is a no-nonsense product in the sense that it doesn't have any LEDs or weird design elements. It's a simple, egg-shaped mouse with a grey/silver Logitech logo towards the back of the unit. 

The lack of RGB lighting (which is something that the G Pro and G203 does have) was almost certainly a conscious design decision made in order to save weight, and I can only applaud Logitech for that. The only thing that matters with competitive gaming gear is the performance, and while pretty lighting can be nice to look at when the mouse isn't being used to frantically click heads it's not a necessity at all in my opinion.

Logitech G305 Review Mouse


The G305 is a pretty small mouse. It's a little over 6.1cm at its widest point, it's 11.5cm in length, and about 4cm high. It's an ambidextrous mouse (with side buttons only on the left hand side) and it weighs in at 96 grams with the included AA battery, but the mouse feels lighter than that because it doesn't have any cable drag whatsoever.

Weight freaks can significantly lower the weight of the mouse by using a AAA battery with a converter, reducing the weight by about 10 grams already. If you're really serious about this stuff you can also play without the back cover, reducing the weight by yet another 6 grams or so. In summary: the G305 is a small, ambidextrous mouse with a pretty light weight which is made to feel lighter by virtue of the mouse being wireless.

Logitech G305 Review Mouse Packaging


There's really not much to the packaging of the G305. It comes in a small box in the typical Logitech G light blue color, which features some pictures and product specs.

Inside the box you'll find the mouse, an AA battery, a quick start guide, and the user manual, along with an extension cable for the receiver dongle. That dongle is found within the mouse, so don't panic if you don't find it in the box itself. The extension cable is a handy tool for people who have their PC somewhere in a cabinet or 'hidden away' somewhere, so it's nice that Logitech included that. The same goes for the included AA battery. Buy the G305, and you'll be gaming in no time without having to buy extra stuff.

Shape and finish

The G305 is an ambidextrous mouse, as said before. It's a rather low and small mouse as well. One point of discussion with this shell design is the way they've made the sides. As it is they kind of flare outwards towards the top of the shell, but don't really have a curve to help you pick it up, nor are they flat. Some people have reported that this design gives them cramps after prolonged usage, and even though I have no issues with comfort or grip I thought I'd mention it regardless.

The shape of the G305 is kind of hit or miss with some people, so if you're considering this I'd suggest holding a G203, G Pro, or G305 (all of those have the same shape) for a while before deciding, just to be safe. Again though; I had no issues at all with the mouse, even after prolonged gaming sessions. It's not the most comfortable mouse I've ever held, but it also didn't give me any discomfort, if you catch my drift.

I do understand where people who hate the shape are coming from, though. As I said: I never had any problems during my testing, but the mouse did take some time getting used to initially and it doesn't exactly feel like it's built for comfort either. The shape, for me, is just kind of 'there.' I don't hate it or love it, but I do think this is an area where some improvements can still be made.

It's a small and low mouse, so I wouldn't personally recommend it for palm grippers if you have anything over small sized hands. It should be great for other grip styles, and unless you have very large hands you should be able to rather comfortably use this mouse. For reference: my hand is 18.5x10.2 cm.

The mouse is finished with a matte black coating which seems to do the job perfectly. I had the (dis)pleasure of testing this mouse during an abnormally scorching summer heatwave so it was put through a very serious 'sweat test' and I can say with confidence that it handles sweat like a champ. No issues with grip under any conditions whatsoever either.

The G305 has a DPI button located on the top of the mouse, which stays out of the way while gaming, and it also features two conveniently placed side buttons. On the bottom it has an on/off switch and five small mouse feet, which provide a smooth, pleasant, and rather fast glide.

Buttons and scroll wheel

The buttons on the G305 are (as they are on the G Pro) very light. I have a feeling that they're a tad stiffer than what I had on my G Pro, but not by much, so you might need to take some time to get used to the buttons. There's no audible or tangible difference between the left and right click though, and they both provide a very satisfying and snappy response. I've always been a fan of the way the clicks feel on Logitech mice and the G305 didn't change that.

The scroll wheel is fine as well. The steps are easy to feel and easy to use, and the middle mouse button is easy enough to click, which seems like an update over the G Pro. It's not the most amazing feeling scroll wheel out there but it's perfectly serviceable and doesn't do anything annoying (it's pretty silent as well) so as far as scroll wheels go that's all it has to do for me.

The two side buttons might do with a little bit less travel time if I'm nitpicking, but they're responsive enough and produce a clear click once pressed.

Summarizing: full marks for the buttons and scroll on this mouse, with a special mention for the amazing (though very light, so beware if you like heavier clicks) left and right mouse buttons.

Quality and cable

Logitech G isn't really a company that's known for their QC issues so as expected the mouse is built nicely. There is absolutely nothing rattling or shaking about when tapping or flicking the mouse, not even when I really tried to listen for it, so the build quality on my unit is absolutely top notch.

As far as the cable goes, well... There is none. Instead of a cable Logitech uses their LIGHTSPEED technology, which really does work exactly like a wired mouse. Wireless mice used to be laughed out of the park because of the performance crushing input lag they brought along with them, but that's a thing of the past with Logitech. Their LIGHTSPEED technology works exactly as advertised and I honestly couldn't feel a difference between the G305 and its wireless friends when it came to response times. It's an impressive work of engineering and Logitech deserve to be praised for their wireless technology.

Performance and sensor

The G305 uses Logitech's proprietary HERO (High Efficiency Rated Optical) sensor, which has the same performance as their lauded 3366 (Logitech's proprietary version of the flawless 3360 sensor) unit, but delivers these performances at 10x the efficiency, making it ideal to put in (you guessed it) wireless mice. 

You should never take any claim at face value, and certainly not when you're a reviewer so I've been extensively testing the G305's sensor and I have to say that I didn't find any flaw with it at all. There's no discernible angle snapping, smoothing, acceleration, or any of those shenanigans and I've also not managed to make it spin out during my testing. The HERO is definitely a top tier sensor which can stand proudly stand next to its older brother, the 3366. One thing to mention is that you cannot change the LOD (Lift Off Distance) for the HERO sensor, nor can you use Logitech's surface tuning with it. That's not a massive problem for most people but I thought I'd say it anyway.

And then there's the million dollar question: is wireless such a big difference? Why yes, it is. You can alleviate most 'cable concerns' by using a mouse with a great cable (or installing an aftermarket cable yourself) and a mouse bungee, but the freedom of movement you get when using a wireless mouse is something else entirely. It won't you make you a better player or anything like that, but it's definitely a great feeling to not be dragged down by a cable.

This will obviously be subjective, as some people mind cables more than others, but I can safely say that I found using the wired G Pro after using the G305 a chore. It's not 'once you go without a wire, everything else will feel dire' levels of amazing; I still have no problem using a mouse with a good cable (which the G Pro doesn't have, for the record) but I definitely noticed the cable more after going wireless. 

The battery lasts for about 250 ingame hours on high performance mode, and up to 9 months on low power mode, by the way, so you won't be drowning in empty batteries with the HERO sensor.

Logitech G305 Review Sideview


Buying a gaming mouse is like buying a sports car: it can have all the best stuff under the hood, but if you have to tilt your head in order to fit in it you won't be winning many races with it. That was a pretty apt comparison (if I may say so myself) since the G305is a pretty small mouse, built for performance.

If you're a palmer you'll probably want to stay away from this mouse, unless you've got pretty small hands. It works perfectly for other grip styles, provided your hands aren't too large either.

The shape definitely isn't the most comfortable out there, and some people outright can't use this mouse due to cramps, so that's something to look out for as well. I myself had no problems with comfort, but I have to admit that the shape can be improved upon.

This is obviously all subjective, there'll probably be palm grippers out there with shovels for hands who use this mouse without breaking a sweat, so take this with a grain of salt, since it's just a guideline.

Conclusion & Recommendation

The Logitech G305 is a worthy upgrade over the G Pro in my opinion. The latter was (and still is, to be fair) a top mouse when it was released, but it was plagued by a horrid braided cable. Logitech did away with the whole cable thing, put a sensor which is every bit as good as the G Pro's 3366 in their new mouse, and released the G305.

It's a fantastic mouse, with a flawlessly performing sensor, super satisfying clicks, and an impressive battery life of 250 ingame hours on one AA battery. It weighs in at 96 grams but it feels lighter than that because of the fact that it's wireless. You can easily reduce the weight if you use a AAA battery with a converter as well, if you want an even freer feeling.

Almost everything about the G305 is superb, but the shape is somewhat polarizing. It's not the most comfortable mouse out there (and it's also pretty small, ruling out most people with large hands, certainly if you're a palm gripper) and some people can't even use the G305 due to the way the sides are shaped. I myself had no such issues but I do agree that the shape could be a bit better.

Concluding: the G305, if you like (or don't mind) the shape, is an absolute beast of a mouse, and it should definitely be considered if you're in the market for a new piece of kit. Playing wireless is an amazing feeling and Logitech's wireless functionality works as advertised. The G305 comes highly recommended.

I have managed to get mine down to 80g by using a “cheap” aaa battery and a small piece of aluminium foil from the kitchen pantry. The aaa to aa adaptor is 4g.. the cheap Chinese aaa is only 7-8g vs 12-13 on Energizer. I also run hyper glides on it and it is currently on Logitech G240 pad.. a great combo. The G502 on the other hand feels still heavy on the same pad.. so I run that one on AMP500 to compensate..


I have 18.5x 9 cm and use palm grip
Is the g305 worth it ?

ProSettings | Max

It’s not often recommended as a palm mouse because of the small size and relatively flat design so I’m not sure if this is the best option for you. Aside from that it’s definitely a great mouse though.


both G Pro Hero and g305 have the same sensor response?

ProSettings | Max

Yes, both have the Hero sensor.


My hands are 17cm and palm grip, should I go for this or something like the glorious model O-

ProSettings | Max

For palm I’d maybe recommend to take a look at the Zowie S line as that has more of a hump to support your palm. Between those two I would go for the Model O though, the G305 is pretty small for palmers.


what do you think would be better, dm1 fps, zowie s2 or g305 for hands 17.5x9cm?

ProSettings | Max

Depends on your grip type and preferences. I’d maybe skip out on the DM1 FPS though, with that hand size. If you overall prefer small mice the G305 is the one to go for, but if you like a more filled feeling I’d go with the S2.


nice review! it’s the best mouse in the market

ProSettings | Max

Thanks for the kind words!


Is this mouse good for claw grip or I should buy other?

ProSettings | Max

If your hands aren’t too large you shouldn’t have any issue with claw gripping this mouse.


My hand size is 18 x 9 and currently i use claw grip, should i buy this or fk2? Just for csgo

ProSettings | Max

I’d go for the FK2 in that case.


I’ve heard the white is better than the black and that the white is one gram heavier.. know any reasons why?

ProSettings | Max

I happen to have both of them lying around so I pulled ’em out and weighed them. The white one is indeed one gram heavier (coming in at 97 grams with the included battery). This is probably due to the coating on the white one being a different mixture of paints/materials to get that snowy white color, but of course I’m not certain on this. As far as performance is concerned I don’t notice a difference between the two at all.


This mouse is comfortable for me ,if your hands are small,you may try this mouse XD Nice sensor make it fluency and stable.White one is better than black,trust me.

ProSettings | Max

Curious why you’re saying that the white one is better than the black one?


Since i cant really find any information about the noise it makes, i will add it here to help future buyers. I have had wired G1 Gaming for 11y ears and decided to buy G305, it is very nice small and light for my fingertip grip BUT it is loud, it is so loud that i sold it and am back using my G1 which is much much quieter.

Can anyone tell if the G Pro wireless is same or is it quieter?

ProSettings | Max

Loud how? Do you mean the feet on the pad? If so then I didn’t really notice that. I’m not sure if that’s a problem for many people, but thank you for the information obviously!


Just ordered this mouse from amazon and will see how it goes in the long run. However, after reading this review, I am pretty much convinced that i will not be disappointed.

ProSettings | Max

I’m sure you’re going to like it! There’s not much not to love, provided you’re into the shape.


I own one and I´m loving my g305 over the deathadder elite “truck”. The side buttons are not my favourite as i tend to rely on them a lot and they feel kind of weak. It would be perfect if the g305 had the deathadder elite side buttons.. Still, I am loving the g305 and after more than a month of usage in performance mode, the batery level is still … FULL! Amazing mouse!!! Performance wise, no issue at all!! It´s small and has great grip, we always feel under control.

ProSettings | Max

Glad you’re enjoying the mouse! There’s definitely something awesome about wireless mice and if the shape of the G305 clicks for you it’s a dream mouse indeed.


This mouse is awesome! Nice review. Can you also do one for the new G Pro Wireless? Many OWL players have been using it recently.

ProSettings | Max

Good suggestion! We are always adding new reviews to the site and the Logitech G Pro is definitely on our radar.


The cover image when you first visit the site is the fnatic mouse btw
