This slim, modern keyboard and mouse are as comfortable as they are attractive. The keyboard's soft-touch palm rest and quiet keys make it easier to use hour after hour. Microsoft BlueTrack Technology in the mouse gives you precise control on virtually any surface, while the rubber side grips and slightly longer mouse body provide a comfortable feel. This keyboard also features Advanced Encryption Standard (AES) technology, which helps protect your information by encrypting your keystrokes, so you can go wireless without worry.
