Verdict

The Genius Ergo 8100S AI is a right-handed wireless ergonomic mouse featuring 2.4GHz connectivity with a 10-meter range and a lightweight 60g design. It is equipped with silent-click buttons and an optical sensor offering adjustable resolutions of 800, 1200 (default), and 1600 DPI. Key characteristics include specialized dedicated buttons for Windows 11 AI Copilot and voice typing, alongside standard thumb and finger rests for comfort. Its main pros are the silent operation, portability, and AI-workflow integration; however, it lacks Bluetooth support, has a relatively low maximum DPI of 1600, and is not rechargeable, requiring a single AA battery for power.
