Logitech K400 Plus Wireless Keyboard with Touchpad, Black – Model 920-007145
The Logitech K400 Plus is an all-in-one wireless keyboard with a built-in touchpad, designed for controlling a PC, smart TV, or media center from a couch or across a room. It connects through the Logitech Unifying receiver on 2.4 GHz, giving a stable connection up to 10 m (33 ft) away. A 3.5-inch touchpad sits to the right of the keys and handles full mouse functions, so there’s no need for a separate mouse. The keyboard runs on 2 x AA batteries for up to 18 months, and typing stays quiet at under 55 dBA, which matters in shared living rooms or open-plan offices. For Nairobi households running a smart TV off a laptop, or small offices tight on desk space, the K400 Plus replaces two devices with one.
