Overall, pretty good!
Would I buy this product again? Definitely, if they didn't last so long. It's a great quality screen protector, and SO easy to apply.
The only downfall (and the reason I drop a star on my rating) is that when it's packaged, the product gets damaged. I bought two of these because I thought with the first one, it was probably an accident and wouldn't happen again, but it happened with the second one I bought as well. I bought the privacy screen protectors for my Galaxy S8 and both of them came, without fail, with a deep crease in the upper left corner of it, and that's my only disappointment with the product. Otherwise, it works really well.
