It does exactly what it says. Waterproof (I put it in a drain with water and other things). The resolution is sufficient for the tasks it is designed to accomplish. The lighting is excellent. Easy connection with the special app. It requires a little training until you get used to how you should view the camera (absolutely logical). It is definitely worth the money.

Although it is mentioned in the description, there is NO app for iOS, only for Android...
so anyone who has an Apple device simply cannot use it.
