The Kensington Pro Fit Wireless Desktop Combo provides everything you need to turn your workstation into productivity central! The wireless keyboard features a thin-sealed membrane that repels water and other liquids, keeping the wiring safe. It's full-sized with 6 rows of keys, including a numeric keypad, giving the touch-typist a professional experience. The wireless mouse has a high definition 1000-DPI laser sensor, letting you move the cursor around your screen with precision and control. The two-button scroll wheel design is highly intuitive and works equally well for both right-handed and left-handed users. With a 2.4Ghz nano-receiver, your desktop stays uncluttered since there's no wiring to get in your way. And with Plug & Play installation, simply insert the receiver into your device and you'll be up and running in no time.
