I use this camera only when I am taking proctored exams at home for Salesforce certifications through webassessor. They require a USB camera with a long cord and acceptable video quality and microphone. This met all the requirements and was a great choice.
I don't use it for Skype or whatever else people use webcams, so I can't comment on that, but for my every few month need to use this camera in order for someone to watch me and ensure that I'm not cheating - it's perfect. :)
