SteelSeries

Aerox 3 Wireless (2022 Edition)

The SteelSeries Aerox 3 Wireless 2022 Edition is a perforated-shell gaming mouse offered in Onyx and Snow finishes. This record covers the Onyx wireless revision, not the original Aerox 3 or the later Gen 2 model. SteelSeries specifies a 68 g design, a TrueMove Air sensor and Golden Micro IP54 switches. It supports 2.4 GHz wireless and Bluetooth connectivity, with configurable three-zone RGB lighting. The manufacturer advertises up to 200 hours of battery life, but mode-specific conditions still require confirmation.
