For lean-back wireless control of your laptop—even when you’re connecting it to your TV. You can control your laptop without getting up from the couch thanks to the 10-meter (33 feet) wireless range. The large 3.5" built-in touchpad with multi-touch navigation makes vertical and horizontal scrolling intuitive. Setup is simple, too. You just plug the tiny Logitech Unifying receiver into a USB port with no software needed. You can even add five more compatible devices to the same receiver. The sleek, low-profile keys feel good and barely make a sound. And you can enjoy it all for up to a year without the hassle of changing batteries.
