The film moves well but you have to be patient and be careful: I did not focus perfectly but it's no big deal (we hardly see, it is really very quiet) in However, I obviously have not waited long enough after cleaning and I have a small area on the side that is clearly not bonded well (well it did if we try it and it was not three weeks moved).
Fortunately I did not have to try its strength but you do not lose responsiveness.
In short, very satisfied with my purchase. I do not put 5 stars because the explanations are not great nor French.
