Review on JETech Privacy Screen Protector for iPhone 11 Pro Max and iPhone Xs Max 6.5-Inch - Anti-Spy Tempered Glass Film - 2-Pack: Protect Your Privacy with Superior Quality by Pat Haberman

I have used many screen protectors since my first iPhone. This one is the best. It is easy to install but difficult to install badly. It was easier to pair with the phone than the JeTech protectors I've used on the iPhone 7 through X. It is practically invisible during normal phone use. Tilt it up or down - lying on your back while reading, for example - it's still invisible. However, turning it left or right will activate the privacy feature, starting with a rotation of about 30° in either direction and almost black at 45° or more. It also reduces glare from lights to my left and right. I often carry my phone in the same pocket as my keys; This screen protector was not scratched or damaged by them. Overall I'm even happier with this than the JeTech screen protectors I've used in the past.
