The Logitech MX500 is my favorite mouse, by far. It is extremely comfortable and ergonomic while incorporating functionality seen seldom elsewhere. Having used two of these mice on over 20 different computers over the years, I have never once installed the logitech software for the mouse, in the past it caused smooth scrolling to become extremely slow (purposely,) and annoying! I would recommend this mouse to anyone looking for a quality mouse. Don’t let the price keep you away, you’ll wonder how you ever lived without it once you rest your hand on it for a few hours.

Logitech’s MX500 features MX Optical Engine tracking technology that lets you mouse however and wherever you want, faster, and with great response. A new benchmark in optical systems combines high resolution and high frame rate to achieve superior performance, including an 800 dpi sensor for unparalleled accuracy.

Logitech has also added eight programmable buttons, including the innovative Cruise Control scrolling system, to give you a superior blend of power and convenience, especially in long documents or Web pages. The Quick Switch program selector lets you switch between active programs and documents easily, while two thumb buttons let you easily move forward or back between pages on the Internet. The mouse’s sleek, contoured shape fits snugly in your right hand.
