Corsair M75 Wireless Review

The Corsair M75 Wireless uses a modular design with removable side-button plates, letting players configure the mouse for left- or right-hand use or remove buttons entirely for a cleaner FPS-focused shell.

Removable side-button plates are a genuinely distinct feature in the FPS mouse category, letting one shell serve multiple grip preferences, backed by the Corsair Marksman sensor at up to 26,000 DPI and 2000Hz native polling. Against the Corsair Katar Pro Wireless, covered elsewhere on this site, that simpler mouse skips the modular button plates at a lower weight and price. Against the Glorious Model O 2 Wireless, also covered elsewhere on this site, both target ambidextrous FPS use at similar weight classes.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

  • FPS players who want a configurable shell that adapts to left-hand, right-hand, or minimal-button preferences. This mouse's modular plates are a genuine differentiator over fixed-shell competitors.

Not for

  • Not for buyers who want the simplest possible fixed-shell design. The Corsair Katar Pro Wireless, covered elsewhere on this site, offers that more straightforward alternative.
