This product is very satisfactory in terms of its final use, although it protects the screen without much altering the feel to the touch. It is rather thin and does not scratch the first coming has key (I've seen protective film need to be changed after one week for the same phone). Sending is fast enough. Packaging is not very practical, however, once opened we can not close properly, so it is necessary to store movies in another location.
At installation it is not the most practical film that I've known. Indeed, it is quite difficult to ask for the little tab on the top is not easy to withdraw when the film is placed on the phone, and the film desfois Decole slightly when pulling and bubbles may appear. But it's not insurmountable! We need the helping hands that's all.
BIG PLUS: there is a film to be removed on each dimension.
