The Logitech K400 Plus is a 2.4 GHz wireless keyboard with an integrated touchpad that combines keyboard and mouse in a single device, with up to 10 m of range — ideal for a PC connected to the TV, an HTPC and your sim racing cockpit.
Its 3.5" touchpad with gesture support means you don't need a separate mouse, the low-profile keys are quiet (under 55 dB) and spill-resistant, and the Unifying receiver plugs into a USB port for plug-and-play use (pairs up to 6 Logitech devices). It runs on 2 included AA batteries and offers up to 18 months of battery life with an on/off switch.
