The Spigen patent for applying glass to the mobile phone is excellent, the liquid wipe in the packaging that it gives you to clean the phone from dust and dirt dries somewhat quickly, so be careful to be fast and precise, it is generally recommended although it could have been slightly cheaper...

Great product. Straightforward installation and maximum privacy at the right viewing angle. No complaints.

Overall, it does its job perfectly and your neighbors don't see anything. I saw some comments saying that it makes the screen too dark and such, but no, it doesn't affect it at all. I recommend it!

The three stars are not for the quality of the product, I have been using Spigen glass protectors for years and they are top-notch for the price they ask.
This is the first time I try this particular one and I have noticed that it affects the clarity of the screen. Due to its privacy glass type, the screen seems pixelated, which does not happen with the classic Spigen protectors.
Will I change it? No, because I don't have the regular one available immediately.
Would I buy it again? Definitely not.
In terms of quality/application/texture/everything else, it is fine. It doesn't completely hide the screen, but it makes it so dark that you can't read it from an angle, although you can definitely see a diagram of what you are looking at on the other side.
Hope this helps

It does its job quite well, but if you look from the side, the screen appears very dark to black for the unobservant... However, those in front can see the screen, but it doesn't bother you much because they see it upside down...

Very easy installation as we are used to with the Spigen adapter.

Looking at the glass straight before putting it on, you can tell that it is tinted and not transparent, which means sacrificing a tone of screen brightness!
Also, I feel the touch is a bit strange, something that didn't happen with the transparent Spigen ones
