The Kensington 72117 PocketMouse Pro Wireless Compact Travel USB Mouse is the ultimate traveling mouse packed with the smartest features. Simply pull the receiver from its storage place inside the mouse, and plug it into a Mac or PC via an open USB port. It's the perfect solution for mobile professionals who are dissatisfied with the built-in input devices on their laptops and want a versatile mouse that travels light. The RF receiver for this mouse rotates to fit any port configuration, has a range of up to three feet, and automatically turns off the mouse when stored to extend battery life. The Kensington 72117 features a compact shape that is comfortable for both right- and left-handed use, and a stylish metallic-silver and translucent-black color combination that complements contemporary laptops. More convenient and comfortable than a touch-pad, the Kensington Pocket Mouse Pro has three mouse buttons and a scroll wheel that makes navigation easy. The speed and pinpoint accuracy of Kensington's DiamondEye optical technology allows it to respond to even your fastest movements with accurate tracking and precise guidance, and has the additional convenience of no required cleaning. The Kensington 72117 works right out of the box, with long-lasting reliability that is backed by a one-year manufacturer's warranty. This mouse requires a PC running Windows 98, ME, 2000, or XP, or a Macintosh running Mac OS 10.1.5 or later, though it will still function as a one-button mouse with Mac 8 and 9.
