Gear Head MP1550RU mice

Works perfectly

Small, reliable, good deal

It's small and easy to carry together with my laptop.

Got one for 6 bucks, well, it's just paper weight. Hooked it up and wait until the system recognize the device and installed the driver. After that, it barely moves at all. And when it moves, it just jumping around. I got a microsoft one at the same...

NONE of threm worked. they even reshipped another batch & they didn't work either
