The first one I put on had a quarter sized air bubble near the bottom right corner of the screen. It didn't fit the screen perfectly as intended. I played around with it for a few days, then decided to change it. In the second case, the same thing happened, only in the too-left corner. I tried it on again, it was on all four corners. I have a lot of experience wearing these pieces and almost every time I wear them they are almost perfect. I have bought others that had a better rating and everything worked great. No air bubbles or adhesion problems. I wouldn't recommend them to anyone. Very bad quality.
