Summary: Old design, seems to lack a little in contrast. Controls and features are good. Worth about 8 dollors including shipping. I actually removed mine from the original "round" case and remounted in a plastic project box, using a different lens.
Summary: Some reation it didn't work but latter found something wrong with my computer. I gave the logitech to my friend and recntly I bought usded but decent computer. Since I didn't use the Web camera no comments.
Summary: Easy to install and use. Camera frequently freezes at initial log on then seems to catch up and work normally. Frame by frame is slower than expected. Cam does not work any better or worse than my original 8 year old Web Cam. Worth the minimal price if all you need is a simple cam.
