The Lekkermotion KM220 Wireless Combo includes a keyboard and mouse that utilise a 2.4 GHz wireless connection, allowing you to use them from up to 30' away from your computer. The low-profile receiver stays in your computer and won't get in the way of using nearby ports. The mouse is compact, allowing you to take it on the go if you need to. Both the keyboard and mouse are battery-powered for convenience. Plug-and-play capability means you can simply plug the receiver into your computer and get started right away. The keyboard and mouse are compatible with Windows and Chrome operating systems.
