Bought a cheap $10 USB webcam that didn't have a privacy cover. Luckily on my particular camera they fit like friction onto the protruding lens/eye so I didn't really have to remove the adhesive. The lid didn't latch initially, I had to take a razor blade and remove some flashed plastic and then it closed/latched nicely. It looks a little nicer and more convenient than sticking a sheet of paper over the lens with tape. For the price it's ok.
