Wireless Desktop 8-Button Deluxe Mouse takes navigation and computing efficiency to a new level. Multi-button functionality lets you navigate within and between applications with ease. Use Blue LED technology to navigate on virtually any surface - from glass tabletop to granite countertop. The 2.4GHz wireless performance provides lag-free cursor movement. The mouse connects to the computer via a nano receiver that is small enough to plug in and leave connected - great for computing on-the-go. When not in use, the receiver stores conveniently inside the battery compartment. You can click on the standard left/right button scroll wheel to scroll within web browser or documents without moving mouse. DPI Button controls mouse sensitivity (800, 1200, 1600). Back/forward buttons lets you easily navigate between pages in your browser. Button functionality on the contoured mouse also includes zoom for enlarging fine print and the Windows 8 Home button to launch applications quickly and easily.
