I think it's good that the seller a same five films mitgibt instead of just one; because so you can practice a bit, if you, like me, is not the most skilful before the LORD. After three films I have indeed exhausted that I could not mount bubbles all and all somehow wrong conditions. (You can peel off the film again and try the same again, but that only works a few times, then everything is getting worse.) It was only in the fourth it went well, either because I finally "buckled" or because I had additionally polished the display with a glasses-cleaning cloth. Now I have one in reserve, for the price that's okay. But it took nerve, therefore a point deduction for certainly improvable manageability. The instructions I found also not really helpful, but more confusing; somehow I had to intuitively "find my own way," according to the trial-and-error principle. Therefore, it was really beneficial to have a few "practice sheets" on! :-)
