Verdict

The Corsair M65 RGB Ultra Wireless is a high-performance FPS gaming mouse featuring a durable anodized aluminium frame and a state-of-the-art Marksman optical sensor with a native 26,000 DPI, 650 IPS tracking, and 50G acceleration. Key characteristics include dual-mode connectivity via sub-1ms Slipstream Wireless or Bluetooth (offering up to 120 hours of battery life), Omron optical switches for rapid response, and a unique six-axis gyro that enables programmable tilt gestures and ultra-low lift-off distance. Its main pros are the highly customizable tunable weight system (adjustable from 110g to 128g), a dedicated sniper button, and a 2,000Hz hyper-polling rate for near-instant input transmission. However, some cons include its relatively high weight compared to modern ultra-light competitors, a stiff rubber charging cable, and a wide shape that may be uncomfortable for users with smaller hands or specific grip styles.
