Review on 📱 Premium Galaxy S21 Ultra 5G Screen & Camera Protector - Tempered Glass, Touch Sensitive, Fingerprint Support, 9H Hardness, No Bubbles [2+2] for Samsung Galaxy S21 Ultra (6.8") by Troy Henkhaus

It seems that the original manufacturer of this screen protector sells it to different companies under their own brand. I say that because I have seen almost a dozen videos on YouTube showing how to install "Glass Screen Pro Protector Premium Tempered" on various devices including several companies of Galaxy S10, S10e, S10+ brands. My problem with this version of Ailibote was this: Revain's description says it contains an alignment field. There was no such frame in my package. There were no printed instructions other than the very small print on the back of the box which was actually wrong. This guide refers to Label 1 and Label 2, but my screen protectors only had one label. There are some stickers in the box that say "Guide Stickers" but nowhere in/on the box is any information on how to use them. I have installed screen protectors on a number of different devices and have had problems trying to use this screen protector. The instructions are one of the worst I've ever seen. Definitely don't buy this version of Ailibote if you've never put a screen protector on your phone.
