Total convinced

I had only concern is how to keep the mobile phone in the four corner brackets. Exposed has found that these corners are processed either metal or hard plastic very strong that the mobile phone can be pressed and then no longer (at normal handling / extreme test I refrain) slips out.

There are all the necessary holes freely accessible, except for the USB / power connector, in this you have to make sure that the water barrier seal is stored sent to the side, because here precisely the USB port has been released to the millimeter.
