The bag is made of leather, artificial leather and plastic. Processing appears solid, but is somewhat imprecise, so that the phone is not exactly sitting in your pocket. This leads then to the fact that many buttons or outlet openings can not be made accurately. The mini-USB port, for example, almost impossible to use.
Unfortunately, the plastic film is on the front, so on the touch screen, very stiff and relatively thick. Of course, the film is to be stable, but I know of other bags better resolved, for example with a little thicker edge for padding and for thinner film. Anyway, you can not make accurate inputs with stylus or plectrum, because the inputs are perceived to be inaccurate by the thickness of the film.
But for me the biggest criticism is the lack of fixing the bag on your belt. The included clip often goes off by itself and the belt loop is fixed with two snaps that had gone so far loosened after only a few days that I was only able to carry in your pocket, the phone. That reminds me also uses the entire accessories catalog no.
