The DX-ECO from Genius, KYE Systems Corp. of Taiwan is an ECO-friendly wireless BlueEye mouse that gives a whole new meaning to the term “batteries not included”, as the state of the art battery-free design renders batteries obsolete! Simply plug the Micro USB rechargeable cable into your computer’s USB port and into the DX-ECO’s USB port and the wireless BlueEye mouse is fully-charged within 3 minutes. What’s more, the built-in ultracapacitor allows the DX-ECO wireless mouse to be recharged approximately 100,000 times.
As for features, it uses the 2.4GHz wireless band for communication using a tiny USB dongle. There are 7 buttons including previous and next thumb buttons, a flying scroll wheel selector, and an adjustable dpi button (800dpi or 1600dpi). The Genius BlueEye technology lets you work virtually anywhere without interference at distances of up to 15 meters. Plus, with a smart storage compartment inside the mouse for the receiver and USB charging cable, you won’t have to worry about misplacing them and it comes in handy when traveling.
Considering this mouse could save you a small fortune on batteries, it’s still reasonably priced at about $40.00. It is available from a variety of on-line retailers.
