I bought the screen, (with at least 3 of 21 bad reviews) to make since the odds a bad buy at just 1 to 7 layers. However, it has been confirmed at the 3rd use that this product appears to have been produced simply too cheap! The screen opened, but buckled a matter of ... The result was a kind of spoiler, which I could not resolve. Thus, the screen goes back and I'll look for another.
So in my experience, a clear recommendation to screen not to buy!
