Very good quality .... foil hang not so simple

So the film is of very good quality. Note also no difference to brightness. Therefore had to adjust anything more. Just as the film is described for laying works not so. Have been several films attached to car windows. Here's a little tip for you: Put the film on one side, and then let it slowly to the tablet and slide with a card again and again over the entire width by 1 cm and indeed all. So they push the bubbles in front of them until the film rests completely. For me it worked so best.
