Microsoft Mouse/ keyboard, Wireless 850 - Black

The Desktop Desktop 850 Wireless Mouse provides wireless freedom at an affordable price.
Enjoy the freedom and convenience of wireless technology. Confidently roam up to 15 feet away from your computer while maintaining a strong wireless connection. Alternatively, take the mouse separately for use with a laptop while traveling, as the transmitter/receiver is conveniently sent to the bottom of the mouse when it's time to pack and go. Setting up the keyboard and mouse is simple - just insert the batteries, plug in the small transmitter/receiver, and start typing! This keyboard also includes the Advanced Encryption Standard (AES), which is designed to help protect your information by encrypting your keystrokes.
