Logitech V400 Laser Cordless Mouse for Notebooks, Orange, USB

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™ 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.

Track on more surfaces. Advanced dual laser technology provides pixel-precise tracking at home and on the go.

Enjoy uninterrupted performance and 5X greater range-even in the busiest wireless environments. 2.4GHz Digital Cordless technology makes conventional wireless obsolete. Control your presentation from across the room!

Work longer. The V400 turns off automatically when the Micro Receiver is stored inside, saving power. A battery indicator light lets you know when your battery is running low.

Toss it in your bag and take it anywhere. With its shock-resistant exoskeleton, rubber panels, and storable Micro Receiver, the V400 is built to withstand the bumps in the road.

Experience powerful fingertip control. With Tilt Wheel Plus Zoom, you can zoom into details and also scroll side-to-side; great for working on large spreadsheets. Conventional Forward/Backward buttons are also fully programmable. Note:
