For S3 Mini I wanted consciously to a protective sheath of Cadorabo. My daughter has a white case of Cadorabo for Samsung Trend Lite for a few months and has been very satisfied. For both cases: the PU is lightly padded outside, feels comfortable and high quality. The phone fits in perfectly and the "new smell" is barely perceptible, and not at all annoying. There are two card slots and including a specialist. Value for money is top!
That there is another way I have experienced in my case for Huawei. The fumes were so bad that I have put the envelope out of the box for good one day after outside before I could use them. The envelope felt very easy and the surrounding Kunstoffrand lößte off within a month, now so that you can see from the side on the inner cardboard. Unfortunately there is no Cadorabohülle for my Huawei. :-(
