ERGO PRO is a combo 2.4Ghz & Bluetooth 5.0 vertical ergonomic mouse. The ERGO PRO has been designed to avoid twisting of the arm and wrist and thus relieve the user during prolonged use of the mouse. The resolution of the sensor can be adjusted from 800 to 4000 DPI on the side of the mouse. It is a rechargeable 6-button mouse thanks to its USB-C port and built-in 1000mAh battery (30 days working time). It can be connected either in 2.4Ghz using a supplied mini receiver or in Bluetooth 5.0 to ensure a wireless connection. Its silent clicks and the USB-C charging cable of 1.4meters will provide you an optimal working comfort.
