The case is great if you want to do any kind of sport, the case is completely sealed for snorkeling, for cons I urge you to add the watertight door RD1pour AKA Action Man Sony that will allow you to have an image perfect. If you have a Sony camera AS30 Action Man and you want to dive and have a good image, you have to invest in this limp and the watertight door, count between 810 and 10 for both.
