I rate here rather the protective glass on the back, because I was sent the wrong product. Pretty good marketing, because I have now decided to keep this ...; D The glass is stable, does not reflect strong and scratch resistant, so keeps its promises. The only drawback is that the glass is a bit too narrow (0.5 - 0.7mm). But that does not bother me further, so it fits at least good and without detachment under my sleeve.
