The worlds first wireless gaming mouse, designed for a nonstop gaming experience. With a power-saving sensor, each Li battery has a 50-hour life for intensive game playing. Its unique, patent-pending technology "Quick-Swap Battery Changing System" simulates gun clip loading, allowing instant battery changing under two seconds. An extra battery can be charged using a multi-functional dock, which also serves as a mouse charger and wireless receiver. Two wires enable an optional wired mode and can charge two batteries at once when connected to the mouse and dock respectively. The symmetrical, ergonomic design means both hands will be comfortable enough for long gaming sessions.
