The film fits almost too well: namely, on the tenth of a millimeter. So you have to fit when attaching very accurately - who do not pay attention exactly who can easily get the impression that the film does not fit. It probably would not hurt, just to make one millimeter "too small", then the attachment would more easily. But: First attached, sits the film 1a exactly. I had doubts as to whether they might reflect something and so reading disturbs: But is not the case. The film protects well without disturbing.
