Gigabyte today slipped in its latest gaming-grade wireless mouse, the ECO500. The mouse connects to its host over standard 2.4 GHz band, and relies on a micro-dongle (included). Apart from its design its 1,600 dpi optical sensor makes it gaming grade. The mouse is powered by two AA batteries, with typical usage, a pair lasts up to a year. The mouse measures 105 (L) x 59.7 (W) x 40.1 (H) mm, its weight varies depending on the batteries used. The mouse features a total of five buttons, including two buttons on the left side (making it a right-handed mouse, despite its otherwise ambidextrous design). A red glowing shape (probably relaying the sensor's LED,) and a DPI adjustment switch deck up its top.
