So I have been using these specific screen protectors for the s10+, then for the s21 ultra, s23 ultra, and now for the s24 ultra.
As an application, and if you follow the instructions, the installation is not very difficult. Be careful with the bubble though.
A trick is to move the bubble to the center and let it touch the screen protector before removing the small support, otherwise, due to the fall, it will create small bubbles that won't go away.
In terms of clarity, I can say that it has never negatively affected the colors or the way the screen is displayed in general.
In terms of hydrophobicity, it's okay, but nothing extraordinary.
The only negative thing I find, which has happened with at least two screen protectors so far, is that if, for example, you have the phone in your pocket and it gets slightly squeezed, it cracks.
I don't know if it's a manufacturing flaw. But it has happened to me with three so far, which you can't really call a coincidence.
It also doesn't scratch easily. Better than the material of the phone's screen.

I had the same protection on my S23 Ultra.
Yes, there are screen protectors with an easier installation process available. But since I was already familiar with the installation process, I had no problem with it. The process didn't take me more than 3-4 minutes to complete.
The phone works perfectly. The screen response seems the same to me as before, and the S Pen works normally.
The fingerprint sensor works perfectly, BUT you will need to re-register your fingerprints.
Also, check the official screen protector installation instructions on YouTube (from the company's official channel). It differs in some points from what some well-known "youtubers" show, and these differences make all the difference in the fingerprint sensor response.
Finally, I would like to note that because I wear polarized sunglasses, the screen appears normally through the glass at common viewing angles. A subtle "distortion" in colors may exist under certain conditions, but this is expected for those using polarized lenses. So personally, I consider it polarized friendly.

I give it a 4 out of 5, for one reason only and that is the installation! Nowadays, most "premium" screen protectors are very easy to install, even for someone with little to no experience.

I made a mistake because when I applied the adhesive, there was a very slight tilt on the surface where I had placed my phone. As a result, the adhesive moved slightly to the left, causing a small amount to be lost. When I applied the screen protector, it created two small bubbles. Due to my lack of experience with this type of screen protector, I was unable to fix it and I was disappointed to have to throw away one of the two that came in the package!

As for the handling, I have no problems at all. It feels like I haven't even put on a glass protector! My fingerprint sensor works perfectly, unlike the ESR glass protector which, although it fit perfectly, required me to scan my fingerprint four times to have a somewhat accurate recognition. With this one, it instantly unlocks after scanning it just once!

At some point, I will remove the case I have, which has a magnet (it affects the use of the S Pen), to test it extensively. However, during the time I tested it before applying the case, it worked flawlessly!

As for the reflection, I will have a better idea in the next few days!
