At first I was a bit skeptical by the customer reviews but I am pleasantly surprised! That's what answers it very easy because the housing 2 is divisible and the turn then make is clicked together. Unfortunately it has lasted several days until the shell was there, but given the time frame yet. For this you can deduct a star, but does not have to. As for the reception (wireless, mobile data, etc.) by the metal case, I can not see any negative change and everything is as before. The shell looks nice and noble, is stable and not easily. I am satisfied and I hope that I have what it long.
