It does its job and darkens the screen quite a bit on the sides, but at the same time, all the fingerprints on the screen are visible and it looks a bit ugly (like dirty). However, when you look at the phone from the front, it looks fine! Also, at first, you will notice a slight darkness on very white backgrounds, but you get used to it.

This particular screen protector is indeed very nice and protective, and it also has easy installation. However, it distorts the image, meaning that if you're watching videos and such, it doesn't work well...
4 stars because it distorts the image

This specific product is truly the disgrace of Spigen. For years, I have been applying screen protectors on my phones by myself, without the plastic guide that appeared in recent years. This particular product is NOT worth it in any case. Having purchased around 8 screen protectors, I stubbornly tried to apply it but still haven't succeeded. It will either be defective, leave residue, or not fit properly on the top right, covering the camera lens. Do not attempt it.

Note: The corresponding privacy screen protector with the matte texture fits perfectly without the plastic guide
