HP 920 ERGONOMIC VERTICAL MOUS

The 920 Ergonomic Vertical Wireless Mouse is designed to keep your hand in a more relaxed, natural upright position as you click, drag, and scroll. An included detachable wrist rest provides additional comfort. Designed to reduce muscle activity by 12%, the mouse is certified by Human Factors and US Ergonomics. The mouse tracks on practically any surface thanks to a sensitive, multi-surface sensor. Other features include a six-month battery life and five programmable buttons. A USB dongle is included for wireless connectivity and operation. Also, this mouse allows you to be connected to three laptops/desktops at the same time over Bluetooth, and to switch between them with just a click as needed.
