An S3 case houses our solar battery on an ocean buoy, definitely an extreme environment.

Also… didn’t know if I ever told you or not, but last year I had a customer in who was looking at my boxes. I was telling them what great boxes they were, how they were waterproof, etc… he looked at me and said, ‘You don’t have to tell me how wonderful these boxes are… let me tell you…’ So he proceeded to tell me that he survived Katrina, and when they got home they still had knee deep water in their yard… he found this box floating back there, and he picked it up and it has a new 35 mm camera in it, still intact… so the box and its contents had survived the storm…
