Overview

The Corsair M55 PRO RGB is a gaming mouse built around versatility. Its ambidextrous design features a symmetrical body with interchangeable side buttons, making it one of the few gaming mice that genuinely works for left-handed players without compromise. At just 86 grams, it sits at the lighter end of the spectrum, which translates to quick, effortless movements across your mousepad — a real advantage in fast-paced games where every millisecond counts. The 12,400 DPI optical sensor delivers accurate, responsive tracking that can be fine-tuned through Corsair's iCUE software.

Under the primary buttons, Omron switches rated for 50 million clicks provide a crisp, tactile response that should hold up through years of heavy use. All eight buttons are fully programmable, giving you the flexibility to set up macros, media controls, or in-game commands to suit your workflow. The multi-zone RGB backlighting adds visual flair and can be synchronized with other Corsair iCUE-compatible devices for a unified setup. Whether you play FPS, MOBA, or MMO titles — or simply want a reliable, comfortable mouse for daily use — the M55 PRO delivers a well-rounded package without unnecessary weight or complexity.
