By envelope arise immediately bubbles on the edge

In the beginning: Delivery everything top, was fast there, beautiful packaging, no question.
However, I have promised me a lot about this film, but was disappointed at the beginning. The application itself was difficult because I did when I wanted to pull off the second layer, at once again complete with the whole film had withdrawn because they clung too tightly to the original film. When I had done everything and all blisters had away (which also went well with the beliebenden aids), then I wanted to make my shell again to the iPad and unfortunately had to find that this was not as easy as I had imagined , Immediately bubbles came back to the edge, since the film fully extends to the edge and is pushed up again immediately, thereby were laboriously reduced bubbles on the edge again, because dirt and dust came from. Previously had not a much cheaper film the problem. So who like me also has a cover that goes over the edge, rather stay away. For the scratch resistance, I can not say much because of low usage.
