I do not like reflective display and wanted to protect the screen. Therefore, I ordered these films. I was a bit skeptical face the low price. For the price you get two films for the display and a cleaning cloth and a map to cross out air pockets. There are also videos on the homepage, such as plotting the ideal foil. I did it as always done: Quite normal in the living room, breathe on display, clean with the cloth, spreading sheet according to instructions on it, Blausen and ready. No blisters, all good and a replacement sheet is indeed still there. The film I like very much. Hardly reflections and a good display image. For my old iPhone 4 I had then bought a very good film for four times the price, this film here is just as good.
