The Logitech Wireless Touch Keyboard K400 eliminates the clutter of using a separate keyboard and mouse, making it the ideal control center for TV-connected computers. Designed for comfortable, lean-back entertainment, it features quiet, low-profile keys paired with a large touchpad that handles multi-touch gestures like scrolling and swiping.

Its advanced 2.4 GHz wireless connection ensures minimal lag or dropouts, even in busy wireless environments. Setup is completely hassle-free; simply plug the tiny Unifying receiver into a USB port to begin navigating Windows, ChromeOS, or Android systems without installing external software. The durable layout is engineered with dedicated media keys for immediate volume and navigation adjustment.
