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 High-Speed Four-Way Wheel: Scroll straight to the end of a long table, then tilt the wheel left or right to pan across wide sheets, so long reports stop being a scrollbar crawl 5 of 9 Programmable Buttons: Map copy, paste, back, forward and DPI switching onto the keys with the free UGREEN software, so the shortcuts you reach for most sit one press away Built for Medium to Large Hands: Sized for right hands with a hand length over 17.5 cm, the 12 cm body supports your palm instead of leaving it hanging, so you can check the fit before you order Settles In Within Two Weeks: A vertical grip with thumb trackball control is a new position, so give it 1-2 weeks of normal use and most people stop noticing the angle and would not go back to a standard mouse
