Even though these newly & luxury case are very cool & stylish, but they can't protect your phone from water damage...
I would highly recommend people to get a waterproof case for your device rather than getting this showoff case...
There are many good looking waterproof case, such this,

Great works Kolibree! Is the brush pad waterproof? Does the iPhone need to be placed closely to the device in order for the app function, would it ever a water droplets on the iPhone screen?
