It doesn't get more hassle-free than this. This light-powered keyboard charges itself whenever there's light-and stays charged for at least three months, even in total darkness. Plus, the free Solar App provides a fun, handy lux meter and more. At only 1/3-inch thick, it looks good-whether you've got a laptop or a desktop. Plus, with its rounded edges and thin profile, this stylish, streamlined keyboard is a joy to hold and behold. All the familiar Mac keys-plus a Mission Control hot key-are exactly where you expect them, including music and brightness controls, command keys and the eject key. And it all works right out of the box. No software installation required. Combining the best of traditional keyboards, laptops and a Logitech-only concave key cap design, you'll enjoy faster, quieter, feel-good typing-hour after hour. The tiny Logitech Unifying receiver is small enough to stay in your Mac so there's no need to unplug it when you move around. And Logitech Advanced 2.4 GHz wireless connectivity keeps you connected with virtually no delays or dropouts. Check out the Logitech Solar App available for download at logitech.com/k750/solarapp.
