Pros: Build quality, sensor, polling rate, weight customization, software tuning, price, insanely high DPI

Cons: Shipped with bad firmware, stiff "sniper mode" button

First of all I'll say now this won't be the longest review. I'm going to stick with what stood out the most for me. I am by no means a "mouse connoisseur", ain't nobody got time for that. Or the money for that matter. I like to spend my free time playing the games.

So I guess that leads to my first point, the price. This is a very affordable gaming mouse for what you get. I could not find many other options that appealed to me at this price point and provided all of these features. I was looking for a wide (claw) grip mouse with weight customization, high DPI (to compliment my ultra-wide resolution) and high polling rate. It's always a bonus to have a mouse that looks good, and this one has a pretty cool design, kind of like a space ship escape pod or something. I should also add that this mouse uses a Pixart PMW336x Sensor, which is very similar to the popular PMW3366 found in other high end gaming mice.

When I first plugged the mouse in, I fired up Overwatch and played some quick play / arcade just to get a feel for it. The results were horrendous. I think the polling rate was glitching out and it was having a hard time moving in the correct direction, also a delay on actions / missed actions? Input delay was HUGE. Well, turns out some other people on the web had problems with it, and it required a... firmware update? On a mouse? Well this is definitely a first for me, needing to update firmware on a mouse. I found this a bit ridiculous. Despite being a gamer I am also a developer who dual-boots into Linux half of the time. If I was exclusively playing on Linux (which is possible as CS:GO works on Linux & other games) I would run into some trouble. They specifically say that you need to connect your mouse to a Windows computer in order to update firmware. So yeah, if you are a Mac or Linux user exclusively, you could have some problems. For most this is no issue, but this could probably irk some people.

So after I installed the Corsair Software Utility, I went through and updated the mouse's firmware. I also did the surface calibration & tweaked the sensitivity profiles. This is another thing, if you want to use the full 12,000 DPI you need to customize the sensitivity profiles, as I think the default cap is 9,000. This is not really a big deal and 9,000 DPI is already a bit crazy. I set the lighting to solid red. The RGB lighting features were not something I cared about, although I appreciate choice in solid colors. Most of the customization is only for rainbow color modes. I don't really care to have pulsating rainbow lights when I'm trying to play a game. There is a cool mode where the lights pulse for each action you make, but ultimately that would be a distraction to you or just be some lame way of showing off the coolness of your mouse at a LAN party.

So after I configured my mouse, I loaded up Overwatch again. This time things went incredibly smooth. No input delay was noticeable. I switched DPI modes based on character, and started trying out the Sniping button on the side. This button I am very iffy about. It is incredibly handy and helps you stabilize your cross hairs. After just a few minutes it started to click in my head and I was using it on demand to lock in on peoples faces. It will take some more practice but can be a handy feature. So the part I'm iffy about, is the button is quite stiff. It's clear that they did this to prevent mis-clicks while simply moving the mouse right. However when you're trying to stabilize your cross hairs, a stiff button that requires substantial force to activate can mess you up. I'm not sure if I'll fully adjust to this or not, but this is something I wanted to mention since it is a fairly exclusive feature for this mouse.

So what's the verdict? I give this mouse a 4.5/5. Great value, feature set & hardware, with mild discomfort & initial configuration headaches. There is always room for improvement, but generally Corsair delivered a great product at a very competitive price.


thank you for the review!!!!! i am looking to get this mouse but also looking at the Mionix Castor and the Logitech G502, have you tried those by any chance ?
I have not, but the G502 is a similar mouse (same sensor & button layout). I'm coming from a Logitech G100S which is an inferior mouse (although one of the best budget mice you can buy). I was considering the G502 but honestly liked the look of the M65 more, and it cost ~$15 less (I'm a cheap ass).

Mionix Castor uses 3310 sensor, not 3366. See some discussion here, but the consensus is 3366/3360 is a better option.
im also a cheap ass to a certain extent and also The M65 pro rgb just looks so amazing. I have a logitech G600 for casual stuff and MMOs but its just too big and heavy for FPS games. Also have a K70 RGB LUX keyboard so i am kind of tempted to get M65 pro to keep it all in the same ecosystem. (corsair)
I have an RGB lighted keyboard as well (configurable) and it is definitely nice to match colors up.

For some perspective, some people claim the M65 is heavier then the G502, and if you want a lighter mouse you will definitely end up removing the weights. But at least you have that option, and the build quality is noticeable in the M65. That puts it at about the same weight as G502. The M65 is also shorter then the G502, which personally I don't mind as I have been used to using the tiny G100S for so long it was a fair transition. The grip is similar enough to the CM Storm Xornet I have at work too, wide but somewhat short.

I honestly don't think you would be disappointed with this mouse, nothing beats a side-by-side comparison of course. Glad I could be of any help.
Hmm.. Yeah i think shorter is better for me because right now my G600 is kind of long and it forces my hand to really stretch and curve around it to really get to the edge of the mouse buttons, and then puts strain on my palm
