After scratching the original membrane of the note 20 that comes out of the box, I saw this as a good choice for a membrane without having to deal with UV glass, glue, and the like. Wasted money, after applying it to the screen with the liquid from the package and following the steps from the tutorial video, the membrane peels off from the edge of the screen, after changing it with the second one from the package, maybe the first one was defective, the same thing happened. After the screen dried from the liquid, the membrane seems to be of poor quality and distorts the colors of the screen. For me, the factory one of the note was very good, but I will probably go for a glass with UV

It protects the screen and is compatible with all Spigen cases. The touch and fingerprint function work normally. Its disadvantage is that it creates minimal "watermarks" and it does not do justice to the excellent screen of the Note 20 Ultra

Very good application as the material is elastic and applies easily, covering the curved surface of the screen. It definitely protects against scratches, but I don't think it is satisfactory for impacts due to its thin and soft surface. This is the second one I am putting on, similarly after summer vacations the wear will be more noticeable and it will need replacement. The feeling it gives is excellent and I would put the same one again as many times as needed.
