Buy screen phone is often the lottery, and those sold by both suggest that the second will be there to catch the attempted installation of the first ... With this protects screen, no such problem. This is the easiest to install that I I've seen to date. Obviously the description of the technology, for which I had some doubts, is really functional because my iPhone has lost absolutely no response and, in addition, it literally just enough to put the protection on the screen to install . No need to fold, roll, or remove air bubbles ... it protects screen is semi-rigid and takes care of everything. It's just fantastic. I bought a bag of the same brand and I think I'll become a loyal user because, at this price, it is impressive.
