The Logitech Wireless Desktop MK300 is free from cords, and full of features. One-touch access controls and programmable F-keys give you fast, easy access to music, video, e-mail and application switching (with the included software). Its 1200 dpi optical mouse makes tracking smoother and more responsive than standard optical mice. Easy-to-setup wireless technology provides a fast, reliable connection right out of the box - just plug the wireless receiver into a USB port on any desktop PC or notebook to get started. You will work in comfort with low-profile, whisper-quiet keys that feel great and barely make a sound.
