The build quality is really top !!! I would have wished, however slightly rounded corners, but that's a matter of opinion. Unfortunately I am not really get up those bags, I wanted to return the sums already and I was really extremely insecure if I keep them .....
.... Now for the "killer feature":
through the micro-fiber cloth has one really in the hands when it brings a tip top clean smartphone from his pocket to 99% of cases.
The friction in your pocket, the display on its own dressing. Before I had often a smeared display. Now I always have a clean One Plus One which looks as if it'll be just out of the factory. I love this feature so much now that I do not want to miss the Fitbag. Since the fabric is slightly thinner you need now slightly longer to the phone to put in the envelope. In the beginning a lot of me is still quite difficult, but you quickly on how to do it best. However, this is removing this more easily.
In addition, the bag matches the Sandstone Black back of One Plus One.
Is your money really worth. I personally would have liked a little rounded corners, but otherwise am very satisfied.
For questions I am happy to help!
