Looking for a thin shell, which is supposed to protect my iPhone 5S from scratches, I chose for this article. After unpacking the cases, my expectations have not been met. All around the shell ridges are present which are also quite sharp sometimes. The burrs can be personalized with course with a fine finger nail file to remove, but there is the risk to scratch the shell and it is also not reach all places without any problems. Furthermore, the housings are located not fit. The iPhone slips a few millimeters in the envelope back and forth - scratches on the back are thus inevitable. Too bad I had to get a better product because of the many positive reviews here hope. Due to the low value, I did not make any return.
