Maximum Ergonomic Comfort

Designed by ergonomics experts, the contoured shape supports your hand, while soft-touch sides provide a comfortable grip.

Most Powerful Optical Technology in the World

Microsoft Optical Technology replaces your old-fashioned mouse ball. It accurately tracks movement by scanning your desktop 6,000 times per second—more than two times faster than any other mouse! Use it on more surfaces* than ever before.

Faster Wheel Scrolling

Move through documents quickly without clicking on the scroll bar. Accelerated scrolling reacts to how quickly you roll the wheel, saving you time and effort.

Forward and Back Internet Buttons

Use the two side buttons to go forward and back in your Internet browser instead of using the toolbar.

All five buttons, including the wheel button, can be easily reprogrammed to perform popular commands with a single touch.
