this phone case claims to be waterproof, shockproof, dirtproof and snowproof. it definitely does all of that and more. I have dropped my phone many times and the screen has never cracked. I have also dropped it in water and it works great. this product is a bit expensive but is worth it. I found that after using it for about 6 months straight it does start to break down but I still continue to repurchase it.
