Verdict

The Trust Bayo II is a vertical ergonomic mouse designed with a 57-degree angle to promote a natural arm and wrist position, significantly reducing strain during long workdays. This eco-friendly device is constructed from up to 70% recycled plastics and features an optical sensor with four adjustable DPI settings ranging from 800 to 2400. Main characteristics include a six-button layout with silent clicks, a 10-metre wireless range via a 2.4GHz USB micro receiver, and a built-in rechargeable battery that lasts up to 3 months. Pros include the ability to use the mouse while charging via the included USB-C cable and its professional, sustainable design. However, notable cons include its right-handed-only orientation, the lack of Bluetooth connectivity (available only on the 'Plus' model), and its fixed ergonomic shape, which may feel too small or slippery for users with larger hands.
