This a great mouse for all games and the 12 buttons on the side are very helpful. The click speed is great and it is a very comfortable mouse. It looks great in person. But the matte black turns glossy after long time use on the front of the mouse and it sometimes you have to re-plug the USB for it to work. The problems aren't to and all in all it is a fantastic mouse

This is a nice gaming mouse. The button response is excellent and it has and its fully customizable. It has a nice soft rubber feel to it and fits well in your hand. Make sure you install the software. There is an extensive control panel that allows you to fully control every aspect of the mouse. Every button has the option to be changed to a long list of functions such as the sensitivity of each as well as double click speed, mouse movement and more. What I found most intriguing about the ability to customize it is that the buttons on both sides are identical so flipping the functions to accommodate a left-hander is a breeze. There are 6 colors you can switch back and forth to with a click of the top button. The colors look great shining through the black exterior. You can set them to breathe or just stay on or you can turn them off. Keep in mind that the colors correspond to your presets if you create any. Lastly it has a nice long and strong  paracord type cord that is extremely tough yet flexible. I could find no cons about the mouse whatsoever.

This mouse is great!  Aside from the fact that it looks totally bad-ass, it's a really great mouse!  It's very easy on my hand, which is good since I have carpal tunnel.  As usual, I promised to let my daughter's boyfriend test this out for actually gaming, programming the buttons, etc. I have personally tested it using Photoshop and I lurve it for that,.  It's smooth and accurate.  I'll update with the gaming use portion of my review, but I just had to give this five stars for what I've already done with it!

This is a great mouse... recomended to me from a fellow gamer while browsing at microcenter.

I needed a new mouse for gaming and after many reviews it came down to the RAT7 or the Logitech GX9.

I have large hands so I wanted a mouse with a wide stance.  The great thing about the RAT7 is that the thumb pad is adjustable... so I knew i could make it fit my hand... the only thing i found disappointing and the reason i gave it 4 stars only for built quality was that after only 2 weeks of gaming, the thumb rail which is adjustable can no longer be adjusted.  the tension that holds it in place is no longer strong enough to hold in place while im gaming.  Lots of people hold a mouse in a lot of ways... i'm a pincher.. I squeeze the mouse between my thumb and pinky and that is how i grip it to move it around rather than resting my palm on the mouse.  The tight grip over days and days of use eventually broke down the resistance that held the thumb rail in place...

Luckily i find the default closed position is quite comfortable anyway so I didn't feel the need to replace it or return it.

Everything else about the mouse is fantastic. from the customizable weight system, and the 4 point customizable DPI adjustment with a toggle button just below the scroll wheel, to the interchangeable parts for the pinky rest and the palm rest.

My favorite feature though which is what sold me over the G9X is the precision aim button.  The little red button near your thumb can toggle lower DPI on the fly.  The way it works is whatever preset you have for your 4 DPI modes, you can set that button to cut that by a % (from 99% to 1%)  so if you have a comfortable DPI setting in an FPS game of 2000DPI and you set the button to 20%, when you press it, your DPI goes from 2000 to 400 and when you let go, back to 2000.  This is a must have for FPS, once you experience it, you'll never go back to any other mouse.

this mouse gets an overall rating of 5 stars in my book and i'm a very picky hardware guy.  I would buy this mouse again for sure.

I bought this mouse for gaming purposes and this is exactly what i needed.
PROS:
--great grip (strictly for large hands as ppl with small hands might feel a bit uncomfortable)
--lighting is excellent (esp the breathing effect of the y logo!!)
--the precision is on point and it has never missed a stroke.
--the buttons are tactile and are very responsive
--the build is durable and feels sturdy.
--on the go dpi changing with a click of a button is really helpful
--the weight is on point and you can add heft to the mouse with the given 5g slotted weights
 CONS:
--the choice of plastic is very bad and considering the price , lenovo could have gone with a better choice.
--software is really confusing at first (check out my video on how to set up KEYBOARD SHORTCUTS( eg: copy , paste, minimize, etc) to the given buttons LINK: https://www.youtube.com/channel/UCezhDJxncKpdF9HjxUrJbRg

--it is a 8 button mouse and not a 9 button mouse . Lenovo on the box says it is a 9 button mouse considering the scroll up and down as a button !!

CONCLUSION:
--Great mouse for the price and if your buying a  gaming mouse for the first time then you can definately get this and out of 10 i would give this mouse a 8.8/10

I love this mouse. And you will too. Cool blue lights and very comfortable in the hand. The only reason I didn't give it 5 stars is the button where you rest your thumb will get accidentally pushed (I have done this a few times in just a few days). It is preset to be a "back" button. It might be able to be disabled but its not that big of an issue for me.

As a gamer I found this mouse to be everything I was looking for. It has a good grip and a decent response on the click. What really shines is the adjustable sensitivity. I would like more than two settings, but the ability to change on the fly with a button right next to the scroll wheel is good. It also has one of those ratcheted/notched wheels so you can select a single movement as opposed to the open rollers where you can slide through a dozen selections at once by brushing it. Firm click on the middle mouse button as well.

I like this mouse a lot, it is suited perfectly for games like World of Warcraft, Diablo, Path of Exile, etc,.. It does exactly as advertised,..
However, it is important to note that this mouse aimed at games similar to the games i mentioned above, generally MMOs, and for FPSs specifically, this mouse might be to complex. The buttons take a bit to get used to if this is your first time with this kind of mouse, but if u have used a similar mouse before, you will immediately notice how easy it is to identify the side buttons without looking. The button lighting is highly customizable and thats a plus.
Again, it does the job that it was intended for perfectly and that's why im giving it 5 stars.

Excellent mouse. It was suggested to me by multiple people. I am very satisfied with the quality of the mouse. All of the buttons are amazing for MMO games especially.

This is a fun mouse to use  due to all the changing colors!  It also works very well with my laptop.  I did not buy it for gaming.  It replaced a mouse that did not work well.
Customer Service was also excellent.
I would buy it again.

This is a great mouse for gaming. I use it every day and I love it! It takes a couple of days to get used the feel of the buttons on the side, but after the initial breaking in period it feels natural to the hand. I also appreciated having the ability to take out or put more weights in. It really lets you have a sense of control to tailor your mouse to have the best reactions to your movement.

I use this mainly for WoW so I spam my hotkeys excessively and have been since early October on this mouse. None of the 18 buttons have shown sign of ware. It fits super comfortable in my hand and the tracking is great. For gaming, this is a great mouse. The textured finish is a very nice touch. Gloss finishes collect the sweat and diet off your hand; just look at the back of a stock Wii remote. This textured finish does not have that issue. The lighting is rgb but I had to find the software online, download the compressed folder, download an app to unzip it, then install it. It was a hassle but nothing to be angry at.

The Logitech g402, is a fantastic gaming mouse, enough dpi to serve my needs. I have relatively small hands and was skeptical about getting this mouse because it seemed to large. After about watching reviews on this mouse for a span of around 4 days, i decided to purchase it. This mouse fit my hand pretty well. It was a bit on the large side at first, but after a week, my hand adjusted to the size and weight (its not that heavy, i was just using an $8 office mouse before this) i really liked it. I play games like borderlands 2, minecraft, skyrim, and some tf2, and this mouse works great at those games. The clicks on this mouse are so nice as well. They require little to no effort to press, and they pop back up almost instantly waiting for you to click them again  There are 5 buttons on this mouse that are actual buttons (excluding scroll wheel and left/right click). The upper two next to the left/right mouse click feel very responsive. The middle 2, about where your thumb rests, I have mixed feelings about. They are somewhat mushy and don't feel as responsive as the ones originally used for dpi changing. The button called the sniper button feels just as responsive as the first 2. Overall this mouse achieved and went beyond all of my expectations. Logitech nailed it on this mouse as a little brother of the g502. The only minor complaints that hardly effect the performance of this mouse at all are the 2 middle side buttons (mouse 4 and 5 i believe). If you are purchasing this mouse and have small to medium hands you have nothing to fear when buying this.

This is a great mouse. The only problem I have is that mine will not recognize the first click while I am playing my game, and only then.
