Thumb Ball, No Arm Travel: Steer the cursor with your thumb while your hand stays put, so you cross a wide screen without sweeping the desk and can work where a mouse would not fit 52 Degrees, Straight Wrist: The body turns your forearm to a natural handshake instead of a flat twist, so the wrist ache a flat mouse builds up over a day never gets started USB-C Rechargeable, Full in 2 Hours: A 500mAh included battery tops up with the included USB-A to USB-C charging cable, so there are no AA cells to swap - and it keeps working while it charges Bluetooth 5.4 and 2.4 GHz, Three Devices: Pair your desktop, laptop and tablet at the same time and switch with one press, so nothing gets re-paired mid-task 40dB Clicks, Built for Shared Rooms: Silent switches keep every click at 40 decibels, so you can work through meetings, lectures and open-plan offices without disturbing anyone
