Built around an ultra-light injection-molded carbon fiber shell and a hollow design, the mouse weighs just 39g and aims to reduce fatigue during long sessions. The single biggest reason to buy is its combination of extreme lightness with a high-end PixArt PAW3950 MAX sensor and multi-mode connectivity, which together deliver fast, precise tracking for FPS and fast-paced titles.

Key Features

Who It's For

The white R5Ultra is aimed at esports and competitive gamers who need an ultra-light mouse for fast aiming and flick shots, especially those who play FPS, battle royale, and fast-action MMO encounters.
