The Microsoft Comfort Mouse 6000 is a wired USB mouse designed for right-handed control over your computer. To enhance your productivity, the mouse features five customizable buttons including a clickable scroll wheel. Microsoft's integrated BlueTrack Technology employs a large blue beam, image sensor and pixel geometry to generate a high-contrast picture of the tracking surface. This allows precise pointing, clicking and scrolling when using the mouse on almost any surface. The mouse is ready for plug-and-play use right out of the box - simply plug it into an available USB port on your Windows or Mac computer.
