JamesDonkey RSR7 Ultra – Shape & Fit Overview
The JamesDonkey RSR7 Ultra is a wireless ambidextrous gaming mouse weighing 43g with dimensions of 120 × 63 × 38.3mm. Its rear-mounted hump makes it particularly well-suited for claw grip styles.
For hand sizing, the RSR7 Ultra fits best for hands measuring 171–218mm in length and 74–90mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.
At 43g, the RSR7 Ultra 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 PAW3950 sensor is a flagship-class optical sensor with flawless 1:1 tracking, zero smoothing, and zero acceleration — the gold standard for competitive play.
