Using Silent Technology, silent click switches and rubber covers, this mouse is truly silent. The 2.4GHz wireless performance allows lag-free cursor movement while the comfort-grip shape provides easy use. Blue LED technology allows you to point and click on more surfaces than other mice - from a glass table to the granite kitchen counter. Silent Mouse connects to the computer via the included nano receiver, small enough to plug in and leave connected so it's great for computing on-the-go. It runs on two AAA batteries and features a USB interface. Mouse is compatible with Windows 7 and higher; Mac OS X 10.4 and higher. More from the Manufacturer
