Review on 📱 amFilm Glass Screen Protector 3-Pack for iPhone 13 / iPhone 13 Pro (6.1" Display, 2021) - Tempered Glass with Easy Installation Tray - Case Friendly by Robert Worlds

All 3 treads have visible imperfections/imperfections that will be visible no matter what I do. Each had something similar to the "smudge" in the top right corner (when the phone is wearing protection). The first thing I noticed after installing it. Tried using the damp cloth that came with it. Still there. It was on the sticky side of the tread. Then I noticed that where there is a small notch for the speaker at the top, the protective film on the left side is increasingly peeling off the screen. I looked at the next one which had a smaller stain but it was sticky and wouldn't wipe off. Finally I use the last rest, the same but fresh sticky.
