then nickel for my c5-03 by cons if you made the same ball as me that is to say stick dust on the film before pasting (it happens because of static electricity) I have a trick works very well ^^ clean the film with water and soap once clean water hunt with a credit card by plating both movie and then turn it as indicated by the instructions on your screen guarantee results more bubbles and it always sticks. for the product in itself has nothing to say he would like his promises and I recommend it.
