Verdict

The Cooler Master MM531 is a right-handed ergonomic gaming mouse featuring a high-performance Pixart PMW3360 optical sensor with adjustable sensitivity ranging from 100 to 12,000 DPI, 250 IPS tracking speed, and 50g acceleration. Built for durability, it utilizes PBT plastic construction and Omron switches rated for 20 million clicks, while weighing a lightweight 92g (excluding the 1.8m flexible cable). Key pros include its comfortable shape for palm and claw grippers, reliable 1:1 tracking with zero hardware acceleration, and extensive customization via three-zone RGB lighting and onboard memory for five profiles. However, some users find the rubber side grips to be slippery over time, and the mouse feet are noted for having relatively high friction on certain surfaces compared to premium competitors.
