I’ll give you a feedback on this. I used the Super Suit official Go Pro case once. The second time I used it (at about -30 meters) it leaked... the camera was off in that moment and it simply didn’t respond to to the buttons. When on the surface I checked it carefully and it was working normally. I asked to experience divers who had this type of cases for long time. I was told there was a gap in the o-ring. Then again I let the camera dry for 1 or 2 days. I checked very carefully camera and case, I closed it with the help of experienced people. Apparently it was fine and well sealed they said. I decided to bring it again about -30 meters. It leaked again. This time it was on and it simply remained on. It recorded continuously all the dive and could not be shut down until I was on the surface. You might think I took a useless risk but there was a videomaker with us. He explained that Go Pro can actually resist much more than -10 meters if it is in a case, even if not perfectly sealed it still protects enough the camera inside even though it doesn’t work properly
