Optical is the "cassette" Pretty good, unfortunately a bit at the edges "fisselig" and frayed, which is not so nice, but overall not very catches your eye. Unfortunately, the shell is very loose, I'm afraid, if it yields more (which is actually common in the material), that I can no longer use, but wait and see. The mobile phone not fall out, but the In / Out in bags they slipped it out quite like .... Overall, however, lends itself good protection, since the shell is quite thick and thus resistant. The thickness is, however, on the other hand evtll. unangenehmt for folks stuck Handy's in his pockets. But value in turn are quite okay.
