Query: Protect my screens

Despite the bad rating, I consider this to be a very good product. As some of other reviewers have said, it does not bring detailed instructions. It does however, have a small tab with some brief instructions on how to peel off the plastic cover that's on it when you first purchase it. The tab might be hard to see for a lot of people, but, overall I think this is a good product that serves its purpose. It has done a very good job of protecting my screens from scratches, and has yet to peel off (like some of the other screen protectors I purchased) despite the fact that I bought this product close to a year ago.
