At first glance, the LifeProof iPhone case just looks like a no-frills scratchguard for your do-everything lifeline. What you don't realise is that it is mil-spec rated - meaning it is waterproof, dustproof, snowproof and shockproof. Most cases that carry out similar functions are considerably more bulky than this one appears to be.
The case will survive 1.8m drops and can be submerged under 1.8m of water. As proof of the LifeProof's ability, they took it out for a day on the beach.
