SteelSeries Aerox 3 Wireless
Score: 91/100Rankings
The Dell Mobile Wireless Mouse MS3320W offers exceptional battery longevity and dual-mode connectivity in an ambidextrous package, but its plastic build, lack of side buttons, and limited sensor performance keep it from appealing to power users.
The Aerox 3 Wireless (Renewed) is a feather-light, right-handed gaming mouse featuring a TrueMove Air sensor, 200 hours of battery life, IP54 protection and fast USB-C charging. It delivers high performance with a low-weight profile, though the honeycomb shell can be slippery and dusty.

Professional reviewers commend the Aerox series for its premium build, ultra-light construction, and the highly accurate TrueMove Air sensor.
