Actually, I did not want to cover. But after my phone (ok, I know it's a smartphone) already three times in three parts lay on the floor (lower shell, battery and device) I thought to myself, try it there with a cheap cover, so that it is no longer so easy to me jumps out of shirts Pants Jacket pocket. I was expecting that comes a fairly thin silicone film which prevents slipping. But far from it. The part has right quality. Stable, very good fit, good feel. On the narrow sides it is like a bumper car with shocks well protected. Of course there will thereby have 2-3 mm thick, but now I can put it on the face, without fear of Kart Zern on the display. And I can do it at an angle somewhere to lay, without it slipping. I'm very satisfied. Even so, it is no longer fell down with ever since.
