It is true, the film is very transparent. But I had, correctly I have problems is to raise the film without bubbles: spots like a Dalmatian. I will again make an attempt at a quiet hour and otherwise buy another slide. With a new copy of the film succeeded much better. But it is not easy to put the film on the headboard so right that she sits ma end of the long road (Smartphone) still flush. This is probably independent of the manufacturer.
