IntelliMouse with IntelliEye is the first mouse to give you superior precision. IntelliMouse with IntelliEye throws out all the old, mechanical technology used in current mice. This mouse uses a new optical sensor that scans the surface beneath the mouse 1,500 times per second to accurately and crisply track the smallest motion. It works on hundreds of surfaces (i.e., no mouse pad required) and stays “brand new” precise because there are no moving parts to wear out or stick. Accuracy - The precise IntelliEye optical sensor tracks movement on just about anything. All the sensor needs is a surface with a small amount of detail, including wood, plastic, or even your pant leg.
Scroll easily - Roll the wheel forward or backward instead of clicking on a scroll bar or arrow.
Precision over time - No moving parts, so your mouse is smooth and precise. Mice that use rubber balls to track movement need to be cleaned frequently because of dust and lint can make the mechanism skip or stick.
Work in comfort - This mouse gives you comfortable support, and the curved sides make it easy to hold with either hand.
Warranty - The IntelliMouse with IntelliEye comes with a five-year hardware warranty.
