What's High Alumina Silicate vs regular tempered glass?
Higher chemical strength. Standard tempered glass is soda-lime; alumina silicate has aluminum oxide chemically bonded into the structure for significantly more scratch and crack resistance. The same chemistry Apple uses in the iPhone's display glass itself.
How easy is the EZ Fit installation really?
Genuinely the easiest install on the market. The tray snaps over your iPhone, you peel the protector backing, press down, and remove the tray. First-attempt success is the rule. No alignment squinting, no stress.
Will it work with my Spigen case?
Yes — specifically engineered for Spigen ecosystem compatibility. The protector has a precise bezel margin so it doesn't interfere with case lips. No lifting at the edges.
Is the protector visible once installed?
Barely. Maximum light transmittance plus an ultra-thin profile means the screen looks almost identical with the protector installed.
What if it cracks?
A cracked protector did its job — it absorbed an impact that would have damaged your iPhone screen. Remove and replace; alumina silicate cracks rather than shatters, so it's safe to peel off.
