3 films in a package are actually a waste, because the idiots (like me) manages the attachment of the film quite easily, without bubbles, without dust inclusions. The effect is fantastic - the device without the film virtually unusable under sunlight and use a pair of sunglasses with polarized lenses, so all the negative effects disappear completely after application of the film.
A top product, well explained and with two spare sheets that no one basically needs - unless you equip more than a Navi.
