Genius Ergo R815 1.0

Ergo R815 is the latest mouse from Genius that is technologically brilliant. Its primary features are 2.4 GHz RF cordless technology, 1600 and 800 dpi switching sensor and a USB battery charger cable.
Ergo R815’s 2.4GHz digital cordless technology provides a longer range of working distance (up to 10 meters away) compared to traditional wireless devices, and delivers interference-free operation. The 2.4GHz mini receiver snaps into the mouse for easy transport and turns Ergo R815 off for power efficiency.
The rechargeable function is distinctive and convenient. You can plug the USB cable to connect Ergo R815 and the PC, and the batteries will be charged while you are using the Ergo R815. Together with the battery charger cable and rechargeable batteries, it saves battery purchases and gives you long-term reliable use.
Advanced high precision 1600 and 800 dpi laser sensor switching can track reliably even on tricky polished or wood-grain surfaces. The laser engine provides incredible more sensitivity for surface and tracking power than an optical device. The 4D scrolling roller and hot keys provide fast access to the multimedia function. With Ergo R815, you will be more productive and efficient.
