Plug and go! Verbatim Commuter Series Wireless Notebook Optical Mice work great for notebook PC and desktop users. With a receiver that's small enough to plug into your computer and leave, these mice offer 2.4 GHz wireless performance, which means no delays in cursor movements and fewer cords to pack. The receiver can be stored inside the battery compartment for safekeeping. A 1,200 DPI optical sensor provides smooth, precise tracking while the sleek design offers a smooth, contoured comfort grip for right or left hand use.
