Given the extremely low price of the product, it would be churlish to be choosy, yes the film is protected only on one side, the one that will be applied on the screen and remove the protection during installation is not provided with the zipper present on more expensive products, the cut is perfect, even as it is too difficult to exactly adjust her pose without being hindered by the edge of the screen, which results in an application imperfect on board (air bubbles) .The scratch resistance seems pretty low, but if the smartphone is in a case that drawback will be significantly diminué..Les delivery times are very short, proof of the company's seriousness. In short, a product that is recommended for those who do not want to ruin the protective films in the often delusional price.
