Received in due time, the product matches the description. It poses as the majority of protective films, namely in a place little, if at all dusty, windless take a little damp cloth, wipe over the screen and gently ask the film, take off the lower part and then remove bubbles with a credit card or similar object, then remove the upper protection. Since the installation, I have not changed my film, it is like new, but I'm not a good example, because I am very careful. Anyway, I recommend this product, although as with all protective films, it's always a galley to ask.
