Engage Wireless Optical Mouse with Nano Receiver – Black

Don't bother. Bought one and it will not work on my computer. Vista version of Windows does not recognize this device.

Decided to buy this with a laptop purchase as it was suggested by the web. Works fine. Only issue is that you really had to force the USB connector in to get it into the computer slot. Thought they were "universal," but this one must have been slightly...

Works great, very comfortable to use, got it on a good deal :)

The mouse worked with no software downloads. Good size. I really liked the magnetic pocket on the bottom for the USB receiver. Has an on and off switch.
