The housing resistant to air, but the "home" button was pressed continuously. I had to tweak it a bit so that is not the case. In fact, it would have been better to have a "transparent" to the entire surface of the phone I like being able to "come out" cables if necessary. It sufficiently tight to air for rain and the phone is "taken" inside a small caoutchou. By cons must remove the other "shell" ... I want to hang this case not on a bike but on a golf cart and suddenly the system to attach to "handle" is a bit small for my needs (but I saw it before buying). The touchscreen responds very well when the phone is hull.
