Before attaching the foil to the back, you should watch the video tutorial is necessarily.
The only way to come to an optimal result.
Unfortunately, the application of the film is connected with a lot of fumbling.
But for skillful hands, this should not be a problem.
The cutouts are exactly where they should be.
A pleasant side effect: The film has the iPad a higher liability, so it does not slip so easily.
The only drawback is the somewhat unpleasant smell of the film and yet somewhat steep price.
Hopefully the smell goes in the next few days.
Altogether there by myself a strong buy recommendation.
