Quick initial thoughts

I am an ex Professional gamer. It’s been many years since I’ve quit, but I still like to perform when I play a game of CS:GO or CoD:MW. This is why a mouse is fairly important to me, I can perform with any kind of mouse after enough time of getting used to one, but I still have my preferences. I’ve always liked to claw grip mice and that’s the main reason I wanted to try out the CoolerMaster MM711.

Most modern gaming mice these days are pretty similiar. Some can even be considered clones. MM711 is not one of them, the shape is unique and it’s based on the CoolerMaster MasterMouse S. I have been using the MasterMouse S at work for around two years. MasterMouse S had a lot of flaws (which is why it’s an office mouse for me), and I got the MM711 hoping for these flaws to be fixed out. And yes, the quality problems that MasterMouse S had on the buttons and the shell are fixed on the MM711 (at least on my unit). Shape is very good for my average/large sized hands (19x10cm).

Technical details

MM711 has PWM3389 sensor from PixArt. One of the best sensors on the gaming mouse market these days. There is no acceleration, minimal lag and little-to-no stuttering. Positioning of the sensor is good and playing with the mouse feels very natural to me. The mouse weights only 60 grams and the weight feels very well balanced.

Buttons are responsive, easy to actuate and tactile. Easy actuation and fast response times arevery important in games, as you are holding a corner in CS:GO or preparing to shoot after an edit in Fortnite. MM711 is equipped with OMRON 20 million+ switches. I would say the clicks on are one of the best I’ve tried, comparable to Endgame Gear XM1 and Logitech G Pro Wireless. There is no post or pretravel and no button wobble (movement from side to side).

MasterPlus drivers have fairly extended configuration options. You can choose from multiple different RGB options, tune the light speed and obviously change the colours. You can have 7 (or less) different DPI levels and change the DPI for each in increments of 100. Polling rate, angle snapping and lod can be changed, the LOD can be also changed by surface tuning your mouse to your mousepad.

Side buttons are very solid, good tactility and again no pre or post travel. They are also well placed, meaning that I don’t have to move my thumb when I am gaming to activate either one of them. Scroll wheel is very good, nice defined and tactile steps, only minus here is that the it’s pretty loud.

Reviews after the initial release were fairly mixed on the MM711, most people had a lot quality issues with the mouse buttons. Cooler Master issued a statement where they promised to work on their quality control. This seems to have been done, as people have gotten more quality units. My unit is pretty much perfect regarding the buttons.

General quality

MM711 feels very well built, the mouse does not make a sound when shaking it and it there is no side or shell flex even when pressing the mouse with quite a bit of force. Cable is extremely flexible, might be even a little bit too flexible where it’s hard to use a bungee in my opinion. Mouse skates have a decent glide, but aftermarket ones would probably make the glide more smooth. I tested the mouse on HyperX Fury S, Zowie G-SR-SE and Glorious XXL Extended mousepads. I can recommed any of these to go with the MM711.

Most importantly, the shape

So yeah, I really like this shape as I already pointed out. The MM711 is mainly designed for claw grippers. Any hybrid grip style works also fine, but if you like to palm your mouse I would not suggest the MM711 for you (unless you have small hands).

MM711 is fairly short, measured 116.5 millimetres and 4.587 inches. Even at this length the mouse does not feel small to me though, and that is because of the width and the pronounced hump towards the back of the mouse. The hump is 38.3mm high and it’s the part of the design that makes this mouse especially good for claw grip.

So I love it. But will this mouse suit you?

If you like claw grip, then yes. This mouse is “claw grippable” with any hand size in my opinion. If you have small hands (about 16x8cm) your grip style with the mouse might fall into the hybrid claw & palm. Where your palm would touch the mouse a little bit more than on normal claw grip.

If you are looking for a small lightweight claw grip mouse, then this is probably your best option. Especially if you have medium or large hands. Easy recommendation especially when considering the price. This can be bought for VERY cheap in the US it seems. Here in Europe MM711 costs about 60 euros.

Conclusion & TL;DR

Is this mouse good? Very much so. I have been using claw grip as my main grip style for many years and I have been looking for a small claw grip mouse. Finalmouse Ultralight 2 and Glorious Model O- are too small for my hands, and they are not that well suited for claw gripping.

MM711 has a very good shape, very good mouse buttons, flexible cable and decent mouse feet. All this packed in to a decent price in Europe and a very good price in the US.

Considering in game performance, I felt I had good control because of the solid palm support provided by the high hump, while still providing good accuracy because of the small form factor. This is a rare combo to find, usually I get more control on bigger mice, but bigger mice feel often clunky when trying to perform fast movements.

I recommend this to anyone either likes claw grip or who wants to try out a claw grip mouse with medium or large hands. For very small hands, the high hump might mean that you will have to use a hybrid palm & claw grip. With this grip style your palm touches the hump a little bit more than on standard claw grip style.

If you happen to own the MM711, what do you think about it? Thanks for the read, any feedback is appreciated!
