The film itself could very well stick to the iPod. It caused no bubbles. But when I wanted to protect the iPod twice with a protective film and silicone sleeve, the film immediately threw bubbles that I could just very difficult to remove. I had the film once deducted, when more bubbles have formed under the film, but the bubbles did not go away, even though I had the display before again thoroughly cleaned. Even with scotch tape, I had stuck to the foil, so that removing the tiny particles of dirt on the film, the bubbles could not be avoided.
Conclusion: For those who just want to protect the screen of the iPod, the film is very good. It fits perfectly on the display. But for those who wanted to have double protection and use a protective sleeve, the film is quite unsuitable.
Maybe it's on the shell, but actually it should not be that the film dissolves at the edges and throws bubbles ...
