With the MK520 Wireless Keyboard and Mouse Combo, convenience and control are comfortably, and literally, right at your fingertips. With softly rounded keys, a full-size layout, one-touch media controls and a palm rest, this keyboard treats your hands right. The mouse keeps your hand supported with contoured sides and soft rubber grips. The mouse and keyboard are so energy efficient you just might forget they use batteries at all. Add to this the advanced 2.4 GHz wireless technology and the use of the Logitech Unifying receiver, and you’re set.
