I've had just about every iPhone case out there and my LifeProof case is by far the best of them all. It's sleek yet extremely durable and doesn't stick to the inside of my pocket like those crappy Otterbox cases do. Knowing that if I accidentally drop it or get it wet and my phone will still be safe is a great feeling. The best part is seeing my friends faces when I dunk it in a pitcher of beer at a restaurant - PRICELESS!
I've had my case for almost a year and it still looks and works great. I wouldn't have any other case.
