First totally perfect applied foil or glass ... I have not had such a good experience. Until normal after about six weeks use the first corner was weggebrochrn suddenly. And soon after, on the side a little bit - and the glass is flat with sharp edges! Then the killer - multiple fractures quasianalogue the Spiderapp. So durable, just four months then exchange Worthy - it too expensive and full-bodied advertised. In addition, it shows the 0.3 mm thick ... So from me to real self-test only two stars.
