The MK270 mouse and keyboard combo by Logitech lets you control your computer from up to 10 metres away with wireless technology. Plug the receiver into a USB port on your laptop and forget about it, for an instant connection every time you turn it on. Advanced 2.4 GHz wireless connectivity virtually eliminates delays, dropouts and interference for more reliability. The full sized keyboard makes typing easy and comfortable, and features a number pad, directional keys and nine F-keys. Eight shortcut keys give you instant access to media controls. The compact mouse is comfortable to use and small enough to carry around with you in a pocket or a laptop bag. The keyboard and mouse both feature on/off switches and extended battery lives. Use your keyboard for up to 24 months and your mouse for up to 12 months without having to change batteries.
