The intersection of class, comfort and functionality. A mouse for the 21st century.
• Comfortable and classy. Tired of using the traditional grip? Take a break from overly-clunky or uncomfortably tiny mice. The ergonomically-designed thumb rests and grips fit the contour of your palm for maximum comfort.
• Sleek and Sexy. Turn heads with a futuristic design. Made for increased functionality and comfort, this mouse combines a handshake grip with easy-access buttons and three levels of mouse sensitivity (800 / 1200 / 1600DPI) for improved tracking.
• Easy-access use. Five buttons give you improved control over your computer's systems. Whether dragging and dropping, selecting large volumes of data, or casually gaming, this mouse provides a low-cost, effective solution for multiple computing needs.
• Compatibility: Windows 8 / 7 / Vista / XP / 2000 Linux Mac OS X (The two thumb buttons are not recognized on the Mac OS X.)
