Not the best of picture quality, but a lot of camera for the money. Very nice to use when compared to other bullet cams, everything is inside the one "pipe," no wires to worry about. I have gotten shot three times in the lens and it is working ok.
If you buy it, take out the microfone cover. It won't be waterproof then, but the sound quality will be much better than in stock. If you want to use it in water, you can put the cover back.
