The processing is difficult in need of improvement. The tabs for removing the top "Matrix" film were several films incorrectly mounted (wrong side) and always stuck somewhere else, so that the upper protective film partout not want to break away from the main film.
This has meant that the film, which was initially bonded ideal, several times unnecessarily triggered the display and each time have crept a few specks of dust, which then had to be laboriously removed again.
From the thing that normally do not even take you 1 minute was a struggle for 10 minutes.
And I'm not a novice, have been glued several films.
Now I understand why 3 sets are enclosed - of three will probably match hopefully. From "Made in Ratingen" I expect more.
The film itself is OK, no worse and no better than the others.
The imprecise measurements seem to be an issue of this brand. Two years ago, I have already taken my old EOS 600D, which they do not fit (1 mm too big).
