It comes with all the necessary tools for a perfect application of the product on the mobile phone.
update 07.12.2023 It continues to be flawless.

It did not fall anywhere and the mobile phone has not been hit anywhere, the screen protector had a small crack in the middle of the top part. I have been using it for 3-4 days and I could use it for eight months. Some other companies, obviously for advertising reasons, we won't mention, and the only reason was that it was not properly installed from the beginning and it visually bothered me. Also, one thing that bothers me is that the screen, when wearing polarized glasses, creates a rainbow effect, like an oil spill. I have never encountered this in any other screen material in the last 10 years

Very good screen protector. Better than others I have changed. It is thicker in its cut, but with the specific case I have, it fits perfectly. It has instructions inside for easy installation.

Applies very well! And it is durable. For someone like me who often drops their phone, it has saved me many times. Okay, it happened to break once, but honestly, it suffers in my hands..

Very good quality and perfect application. It comes with a small tool with which someone can remove any air bubbles that may occur during installation.

Simply a perfect screen protector, very durable and easy to install as it covers the entire surface of the phone. I would buy it again!!!

I could have given it a higher rating if it didn't break inside the packaging while trying to remove the plastic. It's possible that the mistake was mine, as I may have forced it more than necessary. Luckily, the breakage was in the upper corner, so I still used it. It applied easily - I still remember the effort of a previous employee with a different glass. For the money it costs, it is very good (the previous one had triple the price).

I have had this phone case for 2 years now! It just got 2 cracks and air entered the top corner of the phone. Unbelievable!

4/5 for the sole reason that it did not fit properly on the edges of any of the 3 devices I placed it on... it leaves this annoying gap next to the front camera which some find acceptable... as a screen protector, it is excellent... durable and the packaging includes many helpful things for cleaning the phone before and after installation...

Easy installation and fits perfectly. It went on an iPhone 11 since it has the same specifications. However, on the first simple drop from the bed to the floor, it cracked in 3 different places. Obviously, the phone's glass was not affected, but the result would definitely be much worse if it fell from a greater height and on a rough surface. I expected more durability from Spigen.

Update: It started peeling off 5 days later. Garbage

It fits perfectly on the mobile screen. It doesn't affect the screen at all. Excellent glass quality. Spigen is generally a guarantee!
