Reviews last updated: November 2026 · How we calculate this

What customers like about Genius Eco 8100

  • Rechargeable internal battery eliminates the need for disposable batteries
  • Can be used while charging via cable
  • BlueEye sensor technology allows tracking on almost any surface, including glass and leather
  • Lightweight and compact design (81g), making it highly portable
  • Ambidextrous shape suitable for both left and right-handed users
  • Eco-friendly design with long-lasting rechargeable battery life

What customers don't like about Genius Eco 8100

  • Limited number of buttons (only 3), which may not be enough for gaming or advanced tasks
  • Lacks a dedicated physical DPI switching button on the unit
  • Fixed or low polling rate (125 Hz) compared to high-performance gaming mice
  • Potential for wireless interference with 2.4GHz WiFi routers in close proximity
  • Basic build quality often described as 'plasticky' in budget segments
  • No onboard memory for saving custom profiles

Verdict

The Genius ECO-8100 is a wireless, ambidextrous productivity mouse featuring a BlueEye tracking sensor that allows for operation on diverse surfaces including glass, leather, and fabric. It offers a resolution of up to 1600 DPI (often fixed or switchable between 800–1600 DPI depending on the region) and connects via a 2.4 GHz Pico receiver. Key advantages include its eco-friendly, built-in rechargeable NiMH battery that supports use while charging and provides a long shelf life of up to 8,760 hours. However, notable drawbacks include its basic 3-button design with no side buttons, lack of a physical DPI switching button on many units, and a standard 125 Hz polling rate which may feel less responsive compared to higher-end productivity or gaming models.
