You pop the tiny Logitech Unifying receiver in your notebook and leave it there. You can even add more devices. Plug it. Forget it. Add to it.—the tiny, wireless receiver that stays in your laptop and lets you add devices as you need them. You can do more, faster with eight hotkeys for instant access to music, e-mail and more. With intelligent power management, you can go years without replacing the batteries. So you can work or play in more places—like your comfy couch—the wireless connection virtually eliminates delays, dropouts, and interference and gives you a range of up to 10 meters (33 feet). Setup takes seconds—you simply plug the wireless receiver into a USB port on your computer and start using your keyboard right away without software. The special coating protects the keys from fading so you can see what you’re typing for years to come.
