MK710 Wireless Keyboard and Mouse Combo is where comfort and productivity go hand-in-hand. The up to three-year battery life for both keyboard and mouse makes this combo so hassle-free you just might forget it uses batteries at all. With Incurve keys and a cushioned palm rest, this low-profile keyboard almost feels like it's custom-made for you. Both keyboard and mouse are connected via the Unifying receiver--the tiny, wireless receiver that stays in your laptop and lets you add devices as you need them.
