I bought this case for the last holiday. On the first day no one has dared us to use the shell, until my old cell phone without the cover charge fell down and the screen went blank. Well, in the shell and in a pot of water. Sealing! From there we have always had our cell phones inside. Meins, of my daughter and her friend. Operation is very simple, sometimes went not take pictures underwater unfortunately .... but we managed thanks Retrica :)
