With a wireless range of up to 10 meters (33 feet), you can turn up the volume of a YouTube video, pause your vacation slideshow, or tweet about the movie you just downloaded; all without getting up from the couch. And 2.4 GHz wireless technology means you'll enjoy it all with virtually no delays: dropouts or interference. Wireless range may vary due to environmental and computing conditions. No need for a separate mouse; this compact keyboard has a large 3.5-inch: built-in touchpad that makes vertical and horizontal scrolling intuitive. Multi-touch navigation makes it easier than ever to point and scroll your way through the Web. It's got large left- and right-click buttons too. Setup couldn't be easier: you simply plug the tiny Logitech Unifying receiver into a USB port, kick back on the couch and enjoy all your laptop entertainment on the big screen. Even the hot keys work right out of the box without software. Plus you can easily add up to five more compatible mice, keyboards and number pads to the same receiver. Whether you're surfing the Web or e-mailing a friend, typing is just plain easy with sleek, low-profile keys that feel good and barely make a sound. They're easier to read and less likely to fade too; thanks to the bold: bright white font and UV coating. You can go a full year doing the things you love without battery hassles. An on/off switch helps you save power when you're not using the keyboard.
