With the Bluebuild Nexum Pro Wireless Mouse, you won't have to worry about your productivity. Simply plug the included USB receiver into your laptop or desktop, and you're ready to go. You can quickly and easily navigate through your browser and programs using the thumb buttons on the side of the mouse. The third thumb button serves as a home button, allowing you to return to your desktop with ease. The indicator light behind the DPI button turns red when the battery is nearly depleted, so you'll know right away when the mouse needs to be charged. You can also adjust the DPI settings between 800 and 1,600. This mouse comes with a 5-year warranty.
