With laser-etched, backlit keys you can see easily in any light, a sleek look, and comfortable, fluid typing, the Logitech Wireless Illuminated Keyboard K800 delivers a brilliant typing experience-day or night. You can type easily-even in the dark-with brightly backlit, laser-etched keys that provide precise illumination that adjusts to suit your needs. Only the characters are illuminated, so you can see just what you need to see without distraction. The PerfectStroke key system helps make every stroke comfortable, fluid, and whisper-quiet, while the concave design and softly rounded edges of the durable Logitech Incurve keys position your fingers properly and invite your fingertips to glide from key to key, hour after hour. Thanks to fast, flexible recharging, you'll never need to deal with wasteful disposable batteries. Instead simply plug in the universal micro-USB cable-you get up 10 days of battery life on a single charge. You can even use your keyboard while it's recharging. Allow three to six hours for full charge. Actual battery life will vary with use, settings and environmental conditions. Rechargeable batteries have a limited number of charge cycles. With sleek lines, a clear edge, and low-profile keys, this streamlined keyboard adds style to your workspace-whether you've got a laptop or desktop. The tiny Logitech Unifying receiver stays in your laptop. There's no need to unplug it when you move around, so there's less worry of it being broken or lost. And you can easily add compatible mice and keyboards to the same receiver.
