I have an iPhone 5 and am seriously considering buying a LifeProof case. The main perk for me would be the waterproof abilities of the case. Before I buy I would like to know two things, first does the waterproofing work every time? I don't want to end up with a soggy phone. Second, are there any other cases that give the same protection, but still have a relatively small form factor? Thanks in advance for all your help!
