Now I know why there are six films in one package. If you have no experience with the assembly, is the first for trying it (dust underneath, fat finger, placed wrong, etc.). The second one then like better, but the third is only then really good. Recommended is perhaps spraying the screen with soapy water in order to cross out this described later as in the instructions with a debit card. The foil is glued to the edges invisible and also interferes with the picture is not as long as one has applied those without air pockets (ie of dust).
