With a full-size sculpted design, the Wireless Mouse M560 cradles your hand comfortably, hour after hour, whether you're a righty or a lefty or use a fingertip or palm grip. The Windows 8 edge menu button offers extra control just where you need it and one-click access to apps, search, settings and more. Use the hyperfast scroll wheel to coast smoothly through the longest documents in free-spinning mode or step precisely through spreadsheets, photo albums or playlists in click-to-click mode. Two extra thumb buttons let you switch instantly between the traditional desktop and apps and full-screen Windows 8 interface. Tiny unifying receiver practically disappears in a USB port and connects multiple compatible wireless devices. Advanced 2.4 GHz wireless connectivity provides reliability of a cord with wireless convenience and freedom for fast data transmission and virtually no delays or dropouts.
