Nillkin Pro Tempered Glass Protector
One of the best tempered glass screen protectors we've found for the Honor 7X comes from Nillkin. This company uses some of the best glass around, and all the latest technology.
Nillkin uses Japanese AGC tempered glass that's only 0.26mm thin, with curved 2.5D edges. This way the glass is smooth on the edges, and won't get caught on anything, peel up, or crack and chip over time. Additionally, they precision-cut the glass slightly smaller than the actual screen. This is done for two reasons, so don't be alarmed when you get it out of the box.
For one, this ensures a case fits without raising up and pulling off your screen protector. For two, the sides are slightly curved, so the protector stops at the curve to ensure a smooth flat surface, where the protector is stable and perfectly attached to your phone. Otherwise, you'd see the iPhone-style "Halo" on the screen protector. Basically, this is one of the best options for your 7X.
