The case is actually processed very well, do not interfere with the burrs in the operation. The ribbing on the side I find ebanfalls very good. The case is solid in the hand. All ports can be accessed. To operate the buttons no recesses is present, but the plastic is incorporated something. For the volume + and - button works quite well. The On / Off switch can, however, push a little harder by the Case. What bothers me already but over time that's that case on the table rests flat and thus you almost can not hear the phone ringing. That's why I always put it face down on the table o_O
