Keychron M5, droitier, design vertical, optique, sans fil RF + Bluetooth + USB Type-C, 30000 DPI, noir

The Keychron M5 is very good for work. Its vertical shape keeps your wrist and arm in a 'handshake' position, which can help prevent strain after long periods of use. It has great build quality overall, and it connects wirelessly with the included 2.4GHz USB receiver or using Bluetooth with up to four devices simultaneously. It has a secondary wheel on the left side of the mouse, which is handy for horizontal scrolling. Its main scroll wheel, unfortunately, lacks a couple of useful extra features, like a free-scrolling mode and L/R tilt inputs.
