Tired of hunching over your laptop to type? This compact keyboard lets you type in more comfort with a layout you're used to. And it's about 20% smaller than our standard keyboards so it fits in your office, your living room or wherever you use your computer. Simplicity at its best. The three-year battery life practically eliminates the need to change batteries. Setup is a breeze too. You just plug the receiver in, pull the battery tab and start IMing smiley faces to your friends and frenemies. Keyboard battery life calculation based on an estimated two million keystrokes/year in an office environment. User experience may vary. Want to turn up the volume on a YouTube clip? Or jump right to Amazon or your Facebook page? It's all at your fingertips with six hot keys and 12 programmable F-keys for instant access to the Internet: e-mail: play/pause volume and more. Logitech Advanced 2.4 GHz wireless connectivity gives you the reliability of a cord plus wireless convenience and freedom-fast data transmission, virtually no delays or dropouts, and 128-bit AES encryption. The tiny Logitech Unifying receiver is small enough to stay in your laptop, so there's no need to unplug it when you move around. Plus, you can easily add another compatible mouse, keyboard or number pad-without the hassle of multiple USB receivers.
