The protective film should be 1mm narrower because it is extremely difficult to ask. No accessory to avoid any air bubbles is provided but a credit card can do the trick ... that said, it's very very hard and the result is ugly. The margin on the product is enormous and must listen qques cents for purchase in China I think. I suggest to protect the screen from the opening of the box with a film of the kind of it for it is better to have a lousy screen scratched but hey, it's a little disappointing.
What especially requires is that manufacturers like Archos etc. finally make screens that do not scratch so easily ... and that there is not!
