Once I received this case, I decided to test if functionality first thing. I placed a piece of folded paper into the case and submerged it in water for over an hour, then began thrashing the case around violently in the water. The seal was not broken at all; the paper was completely dry. I have since then put my iPhone 5(in a defender) in the case along with my wallet and keys (not all at the same time) with incredible comfort, never to be disappointed. A little pricy, but is backed up by the signature Otterbox quality.
Pros: High quality, Durable, value, waterproof, large
