The Targus Wireless Laser Stow-N-Go Laptop Mouse features a stow-and-go USB receiver that attaches securely to the bottom of the mouse for added portability and convenience. The receiver also triggers an On/Off switch to help conserve power when the mouse is not in use for up to 6 months** of battery life. The built in low power indicator light lets the user know when to change the two AA batteries. The integrated tilt wheel* provides 4-way scrolling for easy navigation by enabling users to scroll vertically and horizontally. For added convenience, this laser mouse features a programmable scroll button* which allows you to zoom, magnify and more. This mouse offers RF technology coupled with switchable 1,600/1,200/800 dpi resolution allowing for adjustable cursor speeds, ideal for today’s widescreen notebooks and features a soft-touch design for added comfort during use. The dual-purpose ergonomic design is small enough for travel yet big enough for comfortable desktop operation.
