KENSINGTON 440571 Mouse Gray

We have designed a mouse that not only fits your hand but also your usage style. The ergonomic design for right-handed users provides hours of comfort, and with a choice of four colors, it's also pleasing to the eye. The Pro Fit™ medium wireless mouse is built for years of use and comes with a limited lifetime warranty. The Pro Fit™ medium wireless mouse is perfect for use with desktop computers and mobile devices, and it features a 2.4 GHz nano-receiver that minimizes interference in busy office environments. The receiver is so small that you can leave it in your computer or slide it into the Pro Fit's built-in receiver storage compartment.
The Pro Fit™ medium wireless mouse is large enough to feel substantial in your hand and small enough to easily pack in your travel bag. Wherever you need to be for work, the high-precision optical sensor provides accurate, responsive cursor control on a variety of surfaces. Plus, this mouse runs for up to 12 months on 2 AAA batteries, which are included.
