The Dell KM5221W in black is a wireless keyboard and mouse combination designed to create a clean, cable-free workspace. The keyboard features an English and Russian layout with quiet keys that allow you to type comfortably without disturbing those around you, while integrated tilt legs with two adjustable angles let you set the height to suit your wrist position. Accompanying the keyboard is a symmetrical mouse that works equally well for both left and right-handed users. Both devices connect via a single USB receiver and are built for longevity, offering a battery life that can last up to 36 months, meaning you can work for years without worrying about frequent replacements.
