So for the price, the shell is okay, but it is not as dimensionally stable as I had hoped. On all sides you can comfortably with your finger into it, it is therefore not established to the cell phone, you can see the cover at any time 'open'. It is questionable whether the not eventually wear out and the envelope thus protrudes from the phone. From the thickness I find it really OK, she's beautiful and transparent, at least visually absolutely as I had imagined. If she were still dimensionally stable, there was of me 5 stars.
