Go to the edge quickly again!

The first film I've got it with great difficulty, as it was slightly crooked repeatedly settle through the constant re-arise bubbles and fine dust particles come under, which has annoyed me after a few days because I wanted to have it perfect. With the second film I had fewer problems and if you use a Bumper considers it a lot better, without pulling namely easily the film at the edges again, and again you have blisters. What the mat is I like about this film thus I feel the glide across the screen more comfortable and faster.
