This is more like a waterproof bumper than a case, yet is still supposed to protect your phone against water (and sand, snow and much more). The protective skin is ultra thin and made from double layered thermoplastic polyurethane, making it the only protective skin that is 98% transparent. All the phone' functions remain fully functional and it's the only waterproof skin to have insurance if the phone malfunctions, so it's worth a try for about $10.
