Very easy application that you can't do wrong, even if you try.
You snap the lid with the glass on top, press in the middle with the included tool, pull the tape, and remove the lid.
Note about privacy: It works very well and the reduction in visibility is abrupt from a certain angle onwards (only from left-right, not from top-bottom) and it doesn't prevent you from seeing clearly as long as you hold the phone in front of you.
However, it's worth noting that the phone's brightness seems significantly lower after installation, something I can't compare now, but many times I can't see well at all when I'm in the sun with the iPhone 16e. If privacy is not important to you, and you are not ready to sacrifice brightness, get the regular version.

The first one was placed not correctly and the case was raising the glass off the screen, and the second one i don’t know how was full of bubbles like it was there before… therefore both pieces were wasted

Easy installation, good quality and good feel in the hand.
However, unfortunately for the Greek summer, for me it doesn't work.
It reduces brightness so much that I can't use my phone well under the sun.
Anyone who values their privacy will obviously find it worthwhile.
But I don't find that much value in it.
Unfortunately, I removed it and put on the regular one from the same company.

I don't know what you're saying that it's not good, it doesn't apply, etc. This brand is one of the best screen protectors as always. If you can't apply it by yourself, watch a video; it requires a technique. No bubbles remain, nothing. You clean it well, you pull the dust with the adhesive, you place the frame on the phone for the screen protector, but you leave it for 1 minute, then you remove the frame, and if there are bubbles, you directly press to push them out, and you have absolutely no issues. Perfectly clear screen, I have no words.

Very good application on the screen and very good feel to the touch. Now regarding durability, I will return to clarify in detail after some time has passed. Super easy application and the kit had everything you need. Anyone with no experience can easily use it. The only negative is that it slightly darkens the brightness, of course, but it is noticeable.

It does exactly what it says -PRIVACY- very high-quality material and super easy application with the guide. Four stars because it darkens the screen by about 10%. Not a big deal, personally it doesn't bother me at all.

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
