Cooler Master MM731 – Shape & Fit Overview
The Cooler Master MM731 is a wireless ergonomic gaming mouse weighing 59g with dimensions of 122.3 × 69 × 39.1mm. Its middle-mounted hump makes it particularly well-suited for claw grip styles.
For hand sizing, the MM731 fits best for hands measuring 175–222mm in length and 81–99mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.
At 59g, the MM731 is classified as ultralight. Ultralight mice under 60g are a favorite for FPS players who prioritize fast flicks and reduced wrist fatigue during long sessions.
The PixArt PAW3370 sensor is a flagship-class optical sensor with flawless 1:1 tracking, zero smoothing, and zero acceleration — the gold standard for competitive play. Maximum DPI is 19,000. Polling rate: 1000Hz.
