Not bad....however..... I didn't have it on long before it started getting scratched and pulling up around the sides of the phone. Since the Galaxy S10+ has an edge to edge screen, you would expect the screen protector to be able to stick adequately on the sides. It also got extremely discolored in a short period of time and scratches very very easily.
However, I will say that it does come with a good amount of products for a clean and easy installation. I just think the actual protector itself could be better.
