Logitech V400 Laser Cordless Notebook Mouse- Grey

From the Manufacturer Two key technologies separate the V400 Laser Cordless Mouse for Notebooks from the rest of the pack. First, the V400 is the first mouse to use a dual laser tracking engine. Developed jointly by Logitech and Philips Laser Sensors, the dual laser engine is based on Philips Twin-Eye 231 Laser technology, using two lasers to detect microscopic surface variations. The result is all-terrain performance merged with pixel-precise tracking. The other key technology, Logitech 2.4 GHz Digital Cordless, provides the most powerful and reliable cordless experience available. Unlike conventional 27 MHz wireless mice, which have shorter, less consistent range and can be susceptible to interference from nearby metal surfaces and other mice, 2.4 GHz enables a consistent 30-foot range, virtually interference-free operation, and plug-and-play performance. The V400: Built from the ground up to provide uncompromised mobile performance, wherever and whenever you need it. Features New! All-Terrain Laser Tracks where other mice hesitate. Advanced dual laser technology delivers precision tracking on virtually any surface you encounter. Storable Micro Receiver Plug-and-play receiver slides into mouse for easy transport. Push to eject and power up! Stow it away to shut down. A protective door covers the storage slot when receiver is in use. 2.4GHz Digital Cordless Toss it in your bag and take it anywhere.
