Kensington Pro Fit Wireless Mobile Mouse Sapphire Blue K72421WW

The ergonomic right-handed mouse delivers comfortable, extended use. Perfect for desktop and mobile use, the compact nano receiver that uses 2.4 GHz wireless technology to reduce interference in office environments and can be stored in the mouse itself when not in use. The mid-sized design is large enough to feel just right in your hand, yet small enough to pack easily in your travel bag. The high-definition optical sensor (800-1600 DPI) delivers precise, responsive cursor control on a variety of surfaces. And it operates for up to 12 months on 2 AAA batteries, included.
