Concerned about the longevity of my screen, so naturally I turned to this tempered glass protection. Obviously received on time (Amazon never let me down) I got down to work ... I never got through it with conventional protections: bubble impossible to remove, random poses, etc. But I'm pretty careful! In short, we first clean the screen with the supplied alcohol swab and with the small chamois. It is essential to ensure that no dust, even the tiniest remains on the screen may not see more than that once the protection in place ... Unfortunately that's what happened to me ! So I removed the protection immediately to fix the problem once and handed the glass, the upper left corner no longer adhered to the glass. So it's oneshot! So I grabbed me from the second protection (one of the reasons that made me choose this product over another) and I pose déééélicatement ... And that's fine: no bubble, no peeling, no nothing. I do not know what happens in case of shock (and I hope not me), but that is my well-protected G3. Protection is fine enough to be forgotten. Go there with closed eyes.
