The box is quite stable. This includes a large belt clip which also serves as an additional protection for the front page. Fit is good. It's maybe a little less than one millimeter lost in the margin of the display. Operation is not affected by the protection glass. Only the initial speisung alimentation of the box is a little hard. In order not to damage, I have it looked at a few Youtube videos of users. Minor accidents had already stand and thanks to the box, there was no damage to the S 5
