So what happens when the housing floods?
How do you insure it?
Some people favor little alarms that go in your housing and tell you if there's moisture. That way, if it's just a few drops, you might catch it in time to return to the surface-especially since most floods are going to start near the surface, where there's little pressure on the housing to seal the o-ring. If the camera gets bumped, it might let a few drops in.
Another solution is CAREFULLY inspect the o-ring and mating surface in bright light for hairs, sand and other contaminants before every dive and make sure nothing (like the little string for the lens cap, or the dessicant pack) sticks out where it will get closed up in the o-ring.
