Microsoft® IntelliMouse® Optical is one of Microsoft's best-selling optical mice, featuring a versatile ambidextrous design and supercharged with Microsoft’s new proprietary IntelliEye® optical technology -- the most powerful in the world.

IntelliMouse Optical features silver detailing, Microsoft's signature glowing red underside and taillight, and ergonomic enhancements to provide comfort for left- and right-handed users. Microsoft's IntelliEye optical technology marks a major milestone in the optical mouse category, taking mousing to the next level and giving IntelliMouse Optical unprecedented performance, accuracy and control.

* Most Powerful Optical Technology in the World! Have you ever lost your cursor? You're not alone. Microsoft has a revolutionary new solution -- IntelliEye optical technology. This entirely new, proprietary technology delivers the fastest, most accurate mouse available today. As a result, Microsoft IntelliMouse Optical provides up to four times the performance of other optical mice. This superior technology translates into precise cursor movement and unmatched responsiveness.

* Both left- and right-handed users can comfortably experience the superior performance of Microsoft's new IntelliEye optical technology.

* The new IntelliPoint software enables both PC and Mac users to experience functionality well beyond the typical mouse.

* Replacing the mouse ball with an optical sensor means there are no moving parts to collect dirt, dust and grime and no ball to be cleaned.

* IntelliMouse Optical works on virtually any surface, eliminating the need for a mouse pad.

* Five programmable buttons All five buttons, including the wheel button, can be easily reprogrammed to perform popular commands in your favorite applications with a single touch. For example: The same button can mean “Cut” in Word and “Insert Comment” in Excel. The side buttons are set by default for easy forward and back Internet navigation.

* Accelerated scrolling Users can move through documents quickly without having to click on the scroll bar. Accelerated scrolling reacts to how quickly users roll the wheel, allowing for faster movement through Web pages and computer applications. This allows you to cover more area in less time, increasing scrolling speed on average 28% (on three or more pages).
