For the opening, I have to mention it's the best anti reflective screen protector to buy for sure. I have tried many and flolab is the best one without a doubt.
The installation process was very comfortable and easy, 0 dust was found. After the installation process was done, I observed from many angles how the screen protector looks on the phone, and man, the screen was so clear and detailed. Fits very well with a phone case so don't worry about it. The screen feels super premium to the touch.the only thing that needs to be improved is the price, or at least the price of the shipping, even though if you calculate, it costs 16.3$ per screen protector so it's a little bit make sense, but the shipping cost is 11$ so it's kinda disappointing.
Overall, I'm really happy to have a flolab screen protector for my s24 ultra, because it makes the phone to look and feel premium as f**k.
