Review on 📱 JETech 2-Pack Privacy Screen Protector for iPhone 11 & XR 6.1-Inch, Anti Spy Tempered Glass Film - Secure Your Privacy! by Daniel Anderson

Works as advertised. There is no need to adjust the brightness, but reading at an angle makes it impossible. Someone said in another review that others can see you have your email/messages app open but your neighbor can't read anything, that's an accurate estimate. Warning, this feature (the reason we buy it) made me have to move the phone holder around in the car as the details aren't clear in the GPS app either unless you have it directly in front of you. My holder was fixed in the center of the dash so I had to play around with it. If you have a window vac type holder you should be fine. No positioning tool is provided for placement. Luckily I still have one from the clear tempered glass set I bought earlier and was able to use it for perfect positioning. Of course, you can apply glass without tools, but it's much easier and more accurate with it. I will no longer switch to clear glass.
