Within a couple weeks of purchase, I had this case as deep as 105ft of water for three consecutive days, twice a day. I probably averaged about 50ft for around for an hour per dive. Point? 6 hours of real depth with no problems and spectacular pictures that beyond surprised me from the S200 Camera. Get close to your subject, probably use the flash (I used the auto setting for the most part--and the diffuser thingy on this case) and the camera/housing will do the rest.
Never had a drop get into the housing even though I exceeded the max depth (barely) a couple of times. Follow the instructions, treat the gasket with love, and TEST IT before you subject your camera to it. They walk you through the process in the manual, and it's kinda common sense.
All of the camera controls are very easily accessible, no hint of leaks. There is not cloth bag or anything with the case, so I use a ski-goggle bag. It should also be stored OPEN so the gasket does not stay compressed for long periods of time.
If you use it, you will be happy. Everyone I was with (including a number of people that initially scoffed at the little camera) were impressed with the performance.
Oh yeah, with the camera, the whole things is a little bit negative (it sinks slowly). Not a big deal, but know you won't see it bob to the surface if you let it go.
