The Logitech K800 features sleek lines, a clear edge, and low-profile keys, the keyboard adds style to your workspace - whether you've got a laptop or desktop. It offers a brilliant typing experience, day or night - thanks to backlit keys and PerfectStroke design. You can work or play anytime with laser-etched, backlit keys that are bright enough to let you type in the dark.The keys provide precise illumination, with only the characters illuminated - so you can see just what you need to see without distraction. The keyboard automatically adjusts the backlighting to suit the lighting conditions. Or you can adjust it the way you like it with the press of a button. Sensors also detect your hands as they approach the keyboard to turn the backlight on and off. Every stroke you make will be comfortable, fluid, and whisper-quiet thanks to the PerfectStroke key system. It distributes typing force evenly across key surfaces, making typing effortless. Durable concave keys position your fingers properly, and their softly rounded edges invite your fingertips to glide from key to key, hour after hour.
