Query: Leakage of Bonica camera case

I had a very bad experience with Bonica Sea Explorer camera , but this might be common for Bonica underwater cameras that have similar housing where two halves are held together by the hinge on one side and the latch on the other. 5 days I tried to use it - each time inspecting o-ring very carefully and each time it was leaking. After I returned it to Bonica, they made a test in a pressure camera and declare that it is good up to 100 feet and to prevent leakage one should better clean the o-ring ( O, yes. I did not use a microscope for this, while on a cruise ship).
