Video summary
An unboxing and first-impressions video from a reviewer who already owns several mice and treats them as task-specific tools. His argument is that rotating between mouse styles and hand positions is better than staying locked in one posture all day, which is what he wants to test with the EM01.
Build quality surprised him. He expected less at this price and instead finds a rubberised base that grips the desk, grooves on the palm rest that he describes as a light palm massage, a comfortable thumb position for medium hands, and a metal scroll wheel that he compares favourably with a well-known brand. The main buttons are soft and quiet rather than clicky, which he sees as right for an office.
He also covers the adjustable tilt, the four RGB modes, USB-C charging with no batteries, three-device switching over 2.4G and Bluetooth, and DPI steps of 1000, 1600 and 2400. Two caveats: the wheel cannot be de-clicked, and the design is right-handed only. His shoulder posture at the desk is the reason he keeps using it.
