The mouse supports both USB and PS/2 connections (on both PC and Mac), convenient for those who do not have a free USB connection. With the cool hovering effect caused by the ominous red glow emanating from the optical light, the mouse glides effortlessly across most smooth surfaces. (Yeah, you can ditch that nasty old mouse pad, unless of course, it is a sweet Simpson’s pad!) The mouse has the typical 3-button layout: a right and left button with a scroll-wheel in the center which has the ability to act as a third button.
