I've had this webcam for just over a year now.
It's a very simple yet effecient cam. The picture is good and it does the job brilliantly.
For the price it's at.. if you want a cheap yet cheerful cam, but this one.
The webcam connects to your computer via USB.
It comes with software + drivers disk, so if you're comp doesn't automatically detect it once the cam is in, just pop the disk in and install.
