The Cooler Master MM830 is a versatile wired gaming mouse with several unusual features, including an OLED screen that you can program to display custom bitmaps or system stats and a D-pad side button cluster like those on some game controllers. It feels well-built and has an ergonomic right-handed shape well-suited for a palm grip for all hand sizes and a claw grip for larger hands. This mouse has storage for four CPI profiles you can switch between using the dedicated button behind the mouse wheel. Unfortunately, you can only change the CPI settings by increments of 100. Also, the sensor on our unit is fairly inconsistent and undershoots the set CPI more during quicker mouse movements, and the customization software is only compatible with Windows.
