It is probably fake or of poor quality from this store. All the screen protectors I used left bubbles and were applied crookedly.

While it is a very good application and easy to install, it does not have auto-dust removal. I had to peel it off to remove dust in the middle of the screen, so the glue at the top left got a bit ruined and there is a permanent bubble that won't go away. It's been like this for 2 years now, I didn't even bother.
As for quality, it is satisfactory, but for me the oleophobic coating is nonexistent. It was full of fingerprints from the first day. I give 4 stars only for the durability, the price which is right for 2 pieces, and the fact that after 2 years of daily use it has minimal scratches.

The first glass in the package, despite cleaning the phone and perfect installation, had a dot on it and in the middle, so I had to remove it and use the second glass. In the end, it's either the factory's fault or this particular batch, because the second glass, even though the phone screen was clean, had exactly the same dot! Instead of throwing it away too, I kept it until I could replace it with glass from another brand! Never again Spigen, they've ruined the quality!

very good screen protection.very easy to install on the phone.

No durability, it filled with scratches in a week! This is the second time I'm using it, the first one lasted much longer with exactly the same use, that's why I bought it again. Has the quality of the material changed?

Of the two, the second one fit correctly, and that's because the first one picked up a little dust from underneath, and when I lifted it to remove it, the glass piece didn't fit properly again. Since I change dozens of glass pieces in Spigen daily at work, I haven't encountered this before. The second one fit perfectly.
In conclusion, if for €12 you buy two, meaning €6 each, and both fit correctly, then we would be talking about amazing value for money. But since you have to spend on both to achieve a result, meaning you spend €12 for the one that fits correctly, then I would say it’s worth the money, neither cheap nor expensive. Thankfully they give two together; otherwise, I would have wasted my money.
I would buy it again, yes, but I have been more enthusiastic about my previous purchases from Spigen.

The worst experience I ever had with a product. 13 euros wasted. The first screen protector had a bubble that wouldn't go away no matter what. The second one was applied incorrectly and ended up crooked. I thought it would solve the issue with the screen protector but unfortunately, I was wrong.

It has a spot at the bottom and doesn't allow the glass to fit properly! I thought it was a random problem or my mistake, so I ordered again, but the problem is probably factory-related because the second glass also has the same spot in the exact same place! So it's a factory defect!

Very good quality, very easy installation and also fits perfectly with the case of the same company

Excellent screen protector at an exceptional price. The installation is a piece of cake. The only flaw I find is that because there is a small gap between the case and the glass, dust particles gather and end up getting underneath the glass, causing it to come off. I notice that it comes off in the upper left part of the phone because it comes into contact with the ear.

Amazing installation process makes mistakes impossible. Five stars for this. I cannot comment on durability as I have it on a few hours…

First time I rate a spigen product negatively! The tempered glass is slightly smaller than the screen size and combined with its sharp edges, every swipe up results in "scratching" my finger. Especially if I use the phone without a case or with the Apple clear case, it becomes quite annoying

Very nice packaging with everything necessary for easy installation, including instructions and especially the included plastic guide, which is amazing.

It seems to be of good quality.

The reason I give it 4 stars instead of 5 is because, as shown in the photo, it does not fully cover the screen from edge to edge. It leaves a small gap, leaving the edges of the screen exposed.

Of course, if you put a case on it, the gap becomes even smaller, as shown in the second photo, but I still think it could have a slightly better fit.

Update (16/4/24): I am changing my review to 2 stars because from the first drop, which was less than half a meter high (the phone fell out of my pocket while getting out of the car), it broke at the corner.
