The high definition is great and perfect for Skype calls, well worth the money. Judging by other people's ability to understand me I assume the microphone is doing the trick.
The auto focus does seem to be a bit dodgy in some lighting conditions but not enough to scrap the technology and the hanging clip works fantastically on my LED monitor.
I'd definitely recommend this webcam for anyone wanting to chat online or take some vanity shots. Two thumbs up
