Do these cameras really work?

Even a few grains of sand in the wrong place can make a housing flood. I also learned my lesson the hard way... with a video camera.

I grease (the o-rings that is) and/or inspect carefully before each trip.

Yep, lesson learned and I am letting it dry out for two days. One thing else I learned with this camera, do not shut the view finder and then take it the next day with you on a dive without making sure you open the view finder. It is hard to open the case real quick and open the view finder at 90 feet down
