Logitech MK700

With the Logitech Wireless Desktop MK700, comfort and productivity go hand-in-hand. Concave keys position your fingers properly, and their softly rounded edges invite your fingertips to glide from key to key, hour after hour. This low-profile keyboard features Logitech Incurve keys and a cushioned palm rest. The keys are so comfortable, you'd think they were custom-made to fit your fingers.
Up to three-year keyboard battery life and 12-month mouse battery life. Better power management practically eliminates the need to replace batteries.
Logitech Advanced 2.4 GHz wireless technology dramatically reduces interference with virtually no delays or dropouts. (Compared to conventional 27 MHz wireless technologies.) Includes 128-bit AES keyboard encryption—one of the highest levels of security available. Get all the benefits of a cord, with the convenience of wireless. Range up to 30 feet (10 m).
