Although I have since I've ordered a smartphone always display slides of Mumbi (Samsung Galaxy SII / S IV) and whatsoever was very happy with it, I had before buying these films yes a little afraid. Mainly due to all the negative reviews I had read previously. Well, I've yet ordered me. They also came to relatively fix and I've tried it a spin. I have to say, because I can not fault it. It was super easy, the cutouts have all fitted, air bubbles or other. Consider, I usually need for so 2 sheets until it works ^^ because I can only recommend or shame the other because apparently had such bad luck with so. However, I do not give here the full score, because although it was super easy, I found that the two carrier films but much more relaxed. Some things you should stop but left as they are
