This product claims it will protect your phone even if completely submerged in water...my phone was splashed by a wave at the beach (with case fully secured - all openings were securely closed), and the case allowed enough water to get in to ruin my phone.
The case was very expensive (I paid $90+ for it last summer) and the bulk was inconvenient, but I was willing to sacrifice the expense and the inconvenience for the full protection and am very disappointed that it was for nothing. This case offers no more protection that the sleeker, rubber cases and a glass screen protector, which I have on other phones in my household. (I should mention that my husband has this case as well, and complains that dust and dirt are constantly getting inside his case, requiring frequent cleaning.)
This phone was taken for pictures by the water, rather than the other phones, with the belief that it was better protected. We did not drop or place the phone in water - a wave splashed it. It was not even submerged, which the product boasts and sells itself on being able to handle. Unfortunately, the Lifeproof case did not hold up to minimal contact with water. I do not recommend this case, and certainly do not recommend trusting it will protect your phone anywhere near water.
