Best underwater case for the iPhone 5?

My husband and I are going to Hawaii this August and want to make sure we get some cool under water shots. What is the best underwater iPhone 5 case? I've heard mixed reviews about life proof so I'm just curious.

I swear by then life proof (I have it for
The 4s but don't see how it would make any difference except sizing for the 5).It's a bit of a pain to keep on 24/7 as the screen is slightly harder to hit but I use it when I'm at my cottage or out hiking through the bush, I've dropped it in the lake countless times or been thrown in with it on and it always remains sealed right and works perfectly. Basically if you want to use it short term for your vacation it'll be perfect, it's just not a case you want to keep on every day when it's not needed.

I think there are so many iPhone 5 underwater case are available in the market. I also need one of the iPhone waterproof case. In my country in this type of case are not available yet. So i'm waiting for this product.
