I bought these today at WalMart, and they are terrible. After cutting with a paper trimmer, they were perfect size. Although after VERY careful and slow application, rolling on just a cm at a time, air bubbles would form. I tried rolling the protector on as slow as possible while rubbing from center out with a microfiber cloth. After application, and only rubbing the protector with microfiber, it was scratched past the point of no return. I cannot imagine what this screen protector would look like after a few days of use.
