Microsoft Optical Technology is also available in a variety of Microsoft wireless mouse products. These wireless products enable you to use your mouse without the clutter of yet another cable.

Our wireless optical mouse products also feature breakthrough power-saving technology that significantly extends battery life. Recent testing has shown Microsoft mouse products to have greater than three times the battery life of a major competitor's. And IntelliPoint software, included with every wireless optical mouse, notifies you when your battery is getting low.

The optical sensor performs best on surfaces with detail to track. It will not function on surfaces without visible detail (such as glass) or surfaces on which it has a reflection (such as mirrors or glossy surfaces). The optical sensor may also have difficulty tracking on highly repetitive patterns (such as printed magazine or newspaper photographs, which often are composed of many dots per inch).

Optical technology refers to the use of an optical sensor to track mouse movement, rather than the traditional use of mechanical parts—rollers, pins, and mouse ball. The tiny optical sensor inside the mouse rapidly records and compares images of the desktop, and translates those differences into on-screen cursor movement.

• Snap-in Receiver A small receiver snaps into the bottom of the mouse when not in use. When the receiver is snapped in, the mouse turns off, conserving battery life.
  
• Longer Battery Life Finally, a solution to the top wireless hassle—now you can work longer without interruption. Many users experience six months of battery life!
  
• Wireless Freedom Experience the convenience of wireless keyboards and mouse products, and say good-bye to clutter.
  
• Optical Technology Optical technology refers to the use of an optical sensor to track mouse movement, rather than the traditional use of mechanical parts. As a result, optical mouse products work on most surfaces and offer you better durability, increased speed and accuracy, and consistent performance.
  
• Increased Speed and Accuracy The optical sensor uses digital technology to track pointing device movement, so you'll experience greater accuracy at any speed.
  
• Consistent Performance With no mouse ball or moving parts to keep clean, the optical sensor stays precise, and the mouse and corresponding cursor move smoothly.
  
• Works On Most Surfaces The optical sensor works on nearly any surface*, so you no longer need a mouse pad. You can use it on your desk, the kitchen counter, or even your pant leg.
  
• Less Frequent Cleaning The recessed lens is enclosed and never touches your desk, so you hardly ever have to clean it.
  
• Durability A mouse with an optical sensor lasts longer than a conventional mouse, because it has no moving parts to wear down over time.
  
• Snap-in Receiver Saves Battery Power
• Comfort for either hand
• Convenient wireless portability
