Great film at a real reasonable price

So, I have now bought himself this film and I must say a sharp product at a really reasonable price.
To apply: You have to take a spray bottle, purely to give a splash Spüli for reducing the surface tension, the window and the glass surface properly spray and apply. After applying best with a squeegee rausdrücken the excess water with Gummielippe. This squeegee is also available here at Amazon and you should buy the same to each standard, low-cost blade otherwise arise scratches. The video then shows also how to do it.
Who in the attachment has problems when working upside down, for example, the edges with masking tape, masking what is used also for painters should, then the film bends a not so strong.
So it's all just a matter of technique. Should also be noted that older window glass and acrylic glass types only conditionally suited for this film and would remain at the end of bubbles above.
But I would buy this film definitely be back.
