I bought the Folia for a Nokia Lumia 630. You can apply very easily. One side Remove the protective film, fix, and then remove piece by piece the protector while she runs to the display. As always, of course, work is important as dust-free, otherwise the best film helps nothing. I had some bubbles in it, they were out pushing residue with a credit card. I had seen all the other with other products ... The display was previously very prone to fingerprints, this seems to be getting better with the film. About scratch sensitivity I can not say anything, but when the price is not as critical, as well as two films were included.
