The Mini Wireless Optical Mouse is the ideal travel companion with its advanced optical sensor technology, cordless convenience, and unique design.  You don't even have to worry about losing parts or performance levels, because this mouse was definitely made with the consumer in mind.  The USB receiver actually stores inside the mouse when it's not in use, and all you have to do is pull it out and plug it in when you're ready to use it.  When the receiver is stored inside the mouse, the built-in power saving technology automatically turns off the mouse to extend the battery life.  Feel free to work on almost any flat surface, because the advanced 800-dpi optical technology will be cruising along and working extremely fast to make sure you have an enjoyable experience.  Go mini, wireless, and optical, and after you do you'll never want to go back.
