Transparent covers conceal nothing unnecessarily and ensure that the original appearance of the iPhone 5S is maintained. So it is here. The shell can raise good and possibly decrease again. The fit is also quite good, the bonded display film is not shifted. All ports are easily accessible. The volume control (+/-) and the on / off switch can be somewhat more difficult to operate, but that's not really a problem.
The build quality is top, the price (incl. Postage) also. It is a pity that my previous silicone cases tend after a while to get a yellowish tinge. We'll see whether that's the case here. Otherwise Best Buy!
