The Logitech G7 Cordless Mouse delivers extreme cordless performance with a 2000 dpi laser engine for blinding speed and precision response. The G7's full-speed, bi-directional USB connection sends a blazing 500 reports/second over 2.4 GHz wireless for a bulletproof connection. Dead batteries won't stop you mid-mission, thanks to a five-level power indicator and twin "hot-swappable" Li-ion battery packs that recharge while you're racking up points. Use Logitech's SetPoint software to customize your mouse with advanced features such as game detection and adjustable sensitivity (including independent x- and y-axis settings). The programmable tilt wheel adds an unprecedented level of control and gaming power.
