ZAGG InvisibleShield Glass Curve
Last but not least is the pioneer of screen protectors. ZAGG is one of the first companies to offer such a product, and consistently make some of the best options on the market. However, ZAGG InvisibleShield is expensive. More expensive than Google's own option.
The ZAGG Glass is hardened, tempered and reinforced curved glass that offers impact and scratch-resistance. This is a brand that millions know, use, and trust. If you don't want to risk it with a cheap tempered glass screen protector consider ZAGG.
