The product does its job: to protect the screen. A little rough at first use, after you get used or it was greased by my fingers ... The cuts are well made. Naltère no colors and no darkened screen. By cons for installation without bubbles will require ironing unless I was too optimistic in thinking that there would be no dust by applying the wire directly by removing the manufacturer's ... I would try my luck next time (with 3 films, not big thing to lose) by cleaning the front screen.
