This company went so far as to actually set up an aquarium to show off how well he phone case floats. They could have at least put some fish in there, or a lobster that people could get for free with purchase of the case. At $129, it better come with a bunch of stuff. There aren't any features that would make a phone case worth $129. Sorry, Dick Smith, but your product is busted. One tap to the phone and it'll end up sinking, which is what obviously happened here.
This product is dumb because it's not waterproof, but it floats. When was the last time you gently placed your phone in water, making sure to keep the button-side facing up? When you drop your phone in water it's usually from a high point where no matter how floatable the phone case was, it'll still plunge in.
