I have used Zagg screen protectors for all my devices, and if I need to replace my crack screen protector, not a problem when I can just pay $5 for a replacement. I believe that this is best screen protector on the market today. The great thing about this protector and not just this protector from Zagg but all their screen protectors have a lifetime warranty. After your purchase the screen protector the first thing you do is go to the Zagg website and register the screen protector, because If your screen protector has happens to crack, instead of having to buy a new one, just login into the Zagg website, and order a replacement screen for only $5 which covers shipping or shipping is free I don't remember. They will send you a screen protector, once you received in the mail go to best buy have them remove the old screen protector, and put on the new screen protector. Then you send old screen protector back to Zagg using the yellow envelope that they sent you in the mail. Though, you spend a lot of money for the best screen protector on the market, and if it cracks, order a replacement for $5, and send in the old one, without having to buy a new one each time. I recommend getting the Glass screen protector, NOT the Plastic version.
