Power through your tasks with a premium keyboard and mouse combo. The advanced keyboard is full-sized and comfortable, with smart backlighting and customizable keys. The MX mouse features a speed-adaptive scroll-wheel, a unique thumb wheel and, thanks to its Darkfield Laser sensor, it tracks anywhere, even on glass. Both devices connect via a single Logitech Unifying USB receiver, offering 10m range, Easy-Switch technology and a Bluetooth Wireless Technology connection means you can connect the mouse to a second or even a third computer.
