Review on Premium Ailun Privacy Screen Protector for iPhone 11/iPhone XR 6.1 Inch - 2 Pack Japanese Glass Anti-Spy Tempered Glass in Black - Case Friendly by Alexis Queen

It doesn't cover the screen 100% when viewed from a certain angle, the privacy function really works and you can't see anything. However, you can see a streak of light around the screen protector where the light escapes since the screen protector is no larger than a portion of the display on the screen. It is a good protector and good looking, just a little small. It doesn't consume too much light, even with a fairly dark screen, everything stays crisp.
