ERGO NEXT: 2.4 Ghz vertical mouse for the left-handed. 
ERGO NEXT is a wireless vertical ergonomic mouse. It has been designed to avoid twisting the arm and wrist in order to relieve the user during prolonged use of the mouse. The sensor resolution is adjustable from 1000 to 1600 DPI so you can use the movement speed that suits you best. It is a 6-button mouse that connects wirelessly in 2.4Ghz via the USB-A receiver (and USB-C via its included adapter). The two side buttons will facilitate navigation on your web applications via their integrated “next” and “previous” functions. Its silent clicks will bring you optimal working comfort as well as its built-in 500mAh rechargeable battery.
