As I say in my reviews on Amazon on any of these cams (and I review them all. Amazon even suspended my ability to posts reviews for a while there because I call crap, crap and Amazon wants sales)... they're cheap cams and they come from China. If you get a good one and it's good enough for you, then it's great. Inversely, if you get a bad one, then it's crap. Plain and simple. I buy from Amazon because I can return crap without a hassle.
