This is a great mouse for at this price point. It's pretty comfortable in the hand and has a good number of programmable buttons.

Now for the downside... As soon as you try to install this on a windows 8 (or higher) machine, windows will install it's own generic driver. This renders all of the extra modes and programmable buttons useless. I searched for hours for a solution. I tried different versions of the Logitech software. I read some people were doing fresh installs of windows, just to get the mouse to function, spending hours trying to find registry errors, etc... Don't bother with any of it. It's not going to work. Read on for instructions that work.

Go to the control panel>Device manager>[find your mouse]>right click>properties>update driver. When the dialog box pops up, choose "Browse My Computer For Driver Software." Then, click browse and navigate to to where the "Logitech Gamming Software" is located. In the case of a standard install, it will be located in C:Program FilesLogitech Gaming Software. Finally, click next. Done! It should now be listed as Logitech Gaming Receiver in the device manager. Open the Logitech Gaming Software. You should now be able to use all of the functions of the mouse.

Off the bat, let me just say this is one of the best wireless mice out there with a few minor drawbacks, but if you are looking for a wireless gaming mouse for less than $50 dollars, this is a no brainer.
First, this mouse is wireless and requires AA batteries to operate. HOWEVER, you DO NOT have to use TWO AA Batteries, you can use a SINGLE AA battery. When playing FPS, a single AA is better suited and cut the weight down by about 25 gram from 130 or so to 107 grams, much better for fast action. When playing other games like RTS or MMOA, I think two AA is okay, but you should judge for yourself. 107 grams is pretty much inline with some of the other wired gaming mouse other including the cord weight.
The Logitech Gaming Software is pretty awesome and you can actually customize all the buttons, you can read up on that. I will just give me some quick pro and cons from a user perspective after using it for about six months playing Overwatch:
Wireless, skip the cord and the bungee holder (I can't go back to wired mice any more)
Customizable buttons make melee, reload, and using abilities easy and quick
Decent tactile feedback on the LMB and RMB, not mechanical but good enough.
Shape is pretty comfortable.

Weight quite a bit for FPS with both batteries
Mouse is a bit on the larger side and make not be comfortable for some
Middle click seems to be a common problem, mine seem to have that issue now.
Polling is at 500Hz instead of 1000Hz like some other top end wireless mouse out there.

Conclusion, if you want a wireless mouse and don't want to spend top dollars for the Logitech G403, G900, or G903, I think this will suit your needs.

I've owned this mouse for over three years and have never been gentle with it. It's gone overseas stuffed in a backpack, been used as a makeshift pillow (on those late night gaming sessions where the body quits before the will...), been stepped on, dropped, left in the sun, left in the cold, and has even had an accidental steam spa session in a hotel bathroom. Now it spends its days shoved in a backpack to and from my university.

Like I said, it's never been treated gently. And yet, it's going strong. It's as responsive as the day I got it (there is zero input lag and anybody who tells you differently needs to review the he response rate of the human nervous system, which is slower than this mouse), the lettering hasn't worn off at all, and everything is in perfect working order. This mouse was a good purchase.

Ergonomics: This mouse is comfortable and really holds your hand well. My girlfriend often attempts to The side buttons are easily distinguished from one another and are comfortable to use.

Adjustable DPI: The adjustable DPI buttons are often useful for gaming. As an example, when playing Overwatch I'll set my DPI rather high when using Junkrat but drop it nice and low for Widowmaker. Or, while playing the Witcher 3, I'll adjust my DPI on the fly if I'm fighting, going through conversation options, or navigating my inventory.

Battery Life: I change the batteries on this little guy a few times a year. I can't even tell you how long they last because it's too long to track; it's just not something I ever think about. Logitech bundles the mouse with optional software that will tell you when your battery life is low, as well. It's worth noting here that I [mostly] turn the mouse off when not in use. The mouse is equipped with an energy saving mode that I never use unless my battery begins to die.

Sensor: This mouse can be used on MOST surfaces, with very few exceptions. First, the surface must be flat. Dips or bumps will affect tracking. Second, it can't be wet. Moisture can affect the senor. Besides that, I've yet to find a surface the mouse struggles with. I've even used it on fabric furniture arms for gaming, which wasn't ideal due to drag... but the mouse tracked perfectly nonetheless. I'd be interested to know if anyone else has--if you've had issues, leave me a comment. I'm curious.

Performance: The mouse has a listed response rate of 2ms. Despite the assertions of many hardcore gamers, they cannot detect lag from a device like this; a wireless mouse is absolutely adequate for gaming. The average human brain has a response ceiling at around 12ms, so claiming one can detect input lag on a 2ms mouse is ludicrous.

CONCLUSION: If you want a SOLID gaming mouse that is comfortable, durable, and versatile, that combines outstanding battery life and game-ready performance, I recommend you consider this device. It has never let me down despite the abuse I've leveled against it and I continue to use it to this day. I've had several friends buy them after playing a bit on mine, even when the price ranged between $50-$70. Now at only $40 it's a no-brainer.

Photography is my career, it’s how I make my living. While this is a gaming mouse, I became interested in it because several trusted professional photographic sources listed it as one of the best choices for photo editing and retouching. They also addressed the most obvious question why not use a graphics tablet. I do but like so many other photographers I don’t always find a graphics tablet natural or intuitive to use for certain tasks.


Gaming mice have at least two features that can make them a good choice for photo editing. One is precision, have you ever tried to draw a circle with a mouse? Drawing a circle freehand isn’t easy anyway but it’s a good test if a pointing device can move with precision. This one is one of the best I’ve tried for being able to move it precisely. One of the other top characteristics a mouse needs is low lag, which also happens to be a key feature for gamers. The cheap wired mouse that came with my computer has less lag than any wireless mouse I’ve owned. This one is impressive, it doesn’t need to “wake up” when you start to move it. Having multiple macro buttons is an advantage as well, although not a necessity.


Or I should say why not Logitech. I’ve owned at least 10 Logitech mice and have a love/hate relationship with them. They generally feel the best physically in-hand and have a solid construction. But they are legend for not lasting long and some of the most rock bottom customer support I’ve ever encountered, and of course being expensive. I fought getting this one but switching brands wasn’t working out for me either (I’ve bought 5 mice just this year). The only reason I gave in is for whatever reason they had it priced down with the cheapies so if I didn’t like it I wouldn’t be out much.


How well it works is subjective. I understand that the typical person reading this is more likely to be a gamer and I’m not one, my entire evaluation is based on how well it works for photo editing. As mentioned it feels good in the hand, neither too small nor too large. The shape of the lip on the left side gives it a good sense of control and the shape of the L/R buttons helps reduce one of the most common issues of accidentally pressing them. That lip actually serves two purposes, one is to use my thumb to vary the amount of downward pressure on the mouse which can be very helpful in keeping it from skidding when I’m making very tiny moves. The other is that using that same thumb I can lift up on the mouse to reposition it, which is almost impossible with any mouse that’s shaped like a beetle – I have one mouse that falls out of my hand whenever I try to lift it.

Being able to change resolutions instantly is a big plus for editing tasks and I find I am doing just that several times while working on a project. While researching pro photographers preferences I also found that the SteelSeries mouse pad SteelSeries QcK Mini Gaming Mouse Pad was one of the top choices so I got one at the same time, and it’s true, a mousepad makes a lot of difference and this one works perfectly for smooth precision tracking and minimizing lag. It’s available in several large sizes, a benefit for graphics work.

I can’t think of any downsides yet. I’ll keep my expectations low of it lasting more than a year but if it does I’ll be happy.

I have large hands and need an oversized mouse. I figured I’d go wireless this time around and looked into gaming mice. There were several “no-name” candidates at bargain prices but most had rechargeable batteries, a frequent area of complaints among the reviews. Most had other issues that disqualified them for me. Then my son recommended the Logitech G602.

I don’t game very much so I can’t comment on its performance in that arena. I do some photo editing though, which requires an adjustable DPI and precision mouse movements.

This is a large mouse—I love the size, shape, the oversized thumb rest. It’s comfortable to hold and use. The texture and feel of the mouse is great, though it’s a bit heavy to move. (I have since removed one of the AA batteries which helps with the weight a bit.) Good button placement. It is the most comfortable mouse I’ve ever used. After I dialed in the DPI, pointer speed, and sensitivity I was feeling pretty good about my purchase.

But I started to notice the pointer would freeze at times, especially when making longer distance right-to-left movements. Or the pointer would stutter. Or jump. I tried a lot of things—changed mouse pads, went without a pad, changed the USB port for the mouse’s wireless dongle on my PC, downloaded the Logitech software, etc. etc. but I could not solve the stuttering, freezing pointer problem.

The package contained a USB extension cable with a female end that fits the USB wireless dongle. I was skeptical this would solve my problem—the dongle, when plugged into my computer, was only 22” away from the mousing area. However, trying the USB extension cable was the last thing I could try before returning the mouse. I connected the extension cable and positioned the receiver dongle about 6 inches away from my mousing area, and voila! No more stuttering and freezing. Just smooth, accurate, comfortable mousing. So if your wireless mouse is stuttering or freezing break out the USB dongle extension cable and connect it. It solved my problem.

[Edited to Add: Date today is December 21, 2019. I received this mouse on August 23rd. I started using it immediately. I have been running it with only one AA battery. About 3 weeks ago I started getting pop-up windows saying I should change the battery as it was at 20% battery strength. I continued using it. About a week ago the pop up windows were warning that only 5% of battery remained. Today it finally quit. I measured the battery's voltage and it was 1.06 volts. Using my computer almost every day for about 6 hours of mouse usage per day I got about 2 months of life out of one AA battery (Duracell.)

Purposely waited for over a month to see if I could find any fault to the mouse. I really tried, but I couldn't. I am a bit biased towards functionality over aesthetics, but this looks refined and solid on the work desk. Initially I was worried about the weight and size, but the sensor and its responsiveness is spot on. I didn't realize competitive gaming was really possible on a wireless mouse until I started using the G602.

Friends say it is pretty much the best mouse out there.. but for the price, there is nothing that can beat this one. Sure, G900 should be better in terms of specs, but this mouse really has everything you need. Save the 100 dollars and use it on something other than the maybe 5-10% improvement in your gaming mouse experience.

I am updating this review and eating crow. After browsing for a replacement that could do all the things that I use this mouse for on a daily basis, I simply couldn't find one. I ordered what is my second G602 and am so happy I did.

I work 40-60 hour weeks as a game developer, so my mouse (regardless of the model) gets a ton of use. When the left mouse button on my old G602 started to fail, I was getting ghost clicks and finding it incredibly difficult to keep the left mouse button down. Since my replacement arrived I a bit surprised at the difference vs. the old one. Somewhere along the line I had forgotten what this gem was like when I first ordered it.

I love the weight. I love the programmable buttons on the side, which allow me to play/pause/build games with a quick flick of the thumb. Apparently the bottom of the old one had seen better days as well, as the new one glides along my mouse pad effortlessly.

This mouse pairs perfectly with my G710+ keyboard, and apologies to Logitech (a company whose products I have used for as long as I can remember) for leaving a 3-star review previously. Did the mouse last as long as I'd hoped; not really. But for the price, I got my money's worth and then some... and then some, and then some. To the point I am tempted to stock-pile some of these for the future.

Save yourself some embarrassment when you first change batteries. First, take careful note that both AA's go in the same way. I did notice that because I'm used to 2-battery devices requiring the + and - being opposed (between the two); these have both + and one end and both - at the other. Second - and this is the one I did not know - when you replace the batteries and turn on the mouse using the switch on the bottom, do not expect the laser to light up and, when you see it NOT light up, conclude that the mouse is broken. Yes, I did contact Logitech. Yes, they were polite. Yes, I did feel like a twit. So I'm posting this here to save you possible embarrassment. The mouse is GREAT. My son thinks the side buttons are too close to one another (he uses a Celotes C-12), but I like the buttons close. If you do as well, you'll love the buttons and the mouse. All the buttons work fine, reprogramming is easy, and the mouse shape, size and feel are just right for me. Logitech's Customer Service contacted me promptly. Can't ask for better.

For the price you can't beat it. Technology might have moved on a bit but I own a ton of Logitech mice and this still works wonderful.

It is about the size of the Performance MX. While it doesn't have the literal thumb button the 6 on the side, where the normal 2 (of most mice), are easy to reach and distinguish between each other.

This doesn't work with the unifying receiver. So if you are limited on USB ports this might not work for you. The nice thing it comes with is a USB extension cord. So worrying about the receiver's reception isn't a problem.

It's also a right hand only model. The ergonomics are pretty good but not perfect. I still find the Performance MX and MX Master/Master S2 to be the best in that area.

Customizations are really good for this. There are "11" G keys but I personally believe that you can't count left and right click as G keys (but maybe some of you do program those so it is possible). It has a DPi changer (which is pre programed to two of the 9 keys) and the software is the solid Logitech Gaming software that most will already know well.

Just buy it if you're looking for a good solid desktop mouse.
Note: I am not using this for gaming. I have wired mice and the G903 with wireless charging for that (far right in picture)

I thought I'd give a non-gamer's review of this mouse, for any other drafter/designers or AutoCAD power users. I've been searching literally years for a replacement for my old fully programmable wired Logitech multi-button mouse that finally stopped working reliably. The new ones *say* they are programmable, but even the $100 MX Master will not accept a macro of *my* keystrokes plus enter, but halleluia, this one does. It definitely took some research to figure it out, as the instructions are aimed at gamers only, but search for programming a macro and you'll get it. The shape is not as nice as the MX Master, and the buttons aren't as perfectly located, but for true macro programming of keystrokes I use hundreds of times a day, I'll take the trade-off.
