The film can be really great and I attach as borrowing have it right on paper. The instruction video you have to watch but before! From time it went, until the film sat for the most part went about 10 minutes (it could be super position), the edges lasted a little longer because the film was still very wet there of the glass cleaner. After about 30-40 minutes. was finally the film so dry you could simply press a finger to the device. The film holds really great (even at the edges) !!!
I can only recommend, even if you but is quite expensive!
