Hello, the film itself is not bad, but unfortunately from the beginning was a small speck of dust on the film. I have stuck anyway and you noticed it clear that it is not applied at the point on the display. Only I have excited me, but then I have used an old trick modelers. Wash the slide with water and a drop of dish soap and as long as it is still wet set on the previously cleaned display. This has the advantage that the film on the one hand is perfectly clean and you can still move about half an hour to the next. The water and detergent and dry Hinte leave no residue on the screen. I hope this little trick helps others who are still in my situation or were. So do not throw away the foil equal. Regards Carlos
