This camera performed well, but stopped working after owning it 40 days.  While it worked the video was excellent HD quality; quite surprising for a camera in the $25 price range.  I rated it 4 stars for the functionality while it was working.  Don't know if there's a warranty from the manufacturer, but it's just beyond Amazon's 30 day return policy.
