The film is basically great, can be mounted easily and even dust and bubble free. BUT ... in the middle of forms depending on the weather? Humidity? Air pressure? an ugly stain of the small and easily to a thick, interfering chunk (about 12 x 8 mm) can be. At first I thought I did the film may not be properly installed but it is definitely not for me. Because the problem here had some other and I have the case now two films that have been purchased at a distance of half a year I can probably save a conversion and considering to purchase me a glass protection. I found "oversized" stop for a compact a bit.
