what does the warranty cover?
I just bought a ZAGG - InvisibleShield Privacy Glass Screen Protector for Apple® iPhone® 6 Plus and my screen just cracked in only a week! I am super upset!
make sure you registered your zagg shield on their website. They have a lifetime warranty and will send you a new one. As long as Best Buy installed the first one they will install it again once you get the new shield from Zagg.
