Logitech® M705 Marathon Wireless Laser Mouse, Black

You can power on with the Logitech® M705 Marathon--a wireless mouse that runs for up to three years on one set of batteries. Plug-and-play setup is easy, as all you do is pop in the tiny, leave-in Logitech® Unifying™ receiver and away you go. Laser tracking delivers smooth, responsive cursor control. Its sculpted shape guides your hand to a naturally comfortable position. Hyper-fast scrolling lets you fly through long documents and Web pages with a single spin of the scroll wheel.
