The first major advance in mouse technology since the 1960s. IntelliMouse Explorer throws out all the old, mechanical technology used in current mice. IntelliMouse Explorer uses a new optical sensor called IntelliEye. This sensor 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 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.
Easier Internet navigation - The two thumb buttons act as forward and back buttons in your browser.
Precision - No moving parts, so your mouse is smooth and precise and there's no need to use a mouse pad.
Feels great in your hand - This mouse is designed to support your hand and fingers. The rubberized sides make the mouse easier to grip and more comfortable to use because it requires less effort to hold.
Warranty - The IntelliMouse Explorer comes with a limited lifetime hardware warranty.
