I chose this because the price seemed interesting, I did not have full confidence in my ability to place the film on the screen and I thought that with this set of 5 chances were all on my side. .. The film is not suitable because it exceeds too much, it could be an advantage but in this case, not at all. Indeed, around the screen is not flat, the sides are rounded and plastic is granulated so that the film does not adhere to the edges, at very short notice, it will take off. In addition, the screen itself is not at the same height as the circle which creates an area where the air bubble is inevitable. In short, the seller is not to blame but the product is formally discouraged.
