The first impression was good in continuous use flawed

The case initially makes a very good impression. For the casual cell phone user, the quality is sufficient. But whoever uses the phone frequently or professionally has quickly problems with the rubber coating that is applied to the edges and corners. Over time, the rubber crumbles off, is soft (by the body were) and glued the entire phone. Then the lining and the metal bracket that is around the display triggers is visible.
The pen is not very good and the removable lower right corner (back) then bends off.
Basically a nice despite imitation leather bag, but unfortunately I now need replacement since you are not tenable. For casual and leisure callers the bag is ok I think.
