At first glance, it seemed good in terms of quality. Indeed, the black frame covers a part of the screen as others have mentioned. Also, it is not compatible with the Spigen Rugged Armor case because it finds the glass on top of the case and it detaches. Unfortunately, it ended up being thrown away.

The black border is smaller than the screen and cuts off a bit of the content. It also breaks easily. Not that it won't protect the screen, but if it breaks even with the slightest impact, you'll have to constantly buy new ones...

My review is only for the application on the Xiaomi Poco F2 Pro that I tested.
The black border of the glass does not exactly match the outline of the screen, resulting in cutting off a small portion of the phone's display, to the extent that it hides, for example, the edges of the letters when reading and when they are at the edges of the screen. It's a shame because otherwise it seems like a very high-quality product.

Very good screen protector, you just need to be very careful when applying it so that no dust or bubbles remain on the screen. It is slightly curved at the edges, making it very convenient to use the screen. After a few days, you will think that your screen does not even have a tempered glass protector.

Note: Like all phones with under-screen fingerprint sensors, it is advisable to re-register your fingerprints once or twice after applying the screen protector. The fingerprint recognition may not be as fast or accurate as it was before without the protector

It looks very good. It covers the entire screen unlike an expensive one I had before. Excellent touch response. I had 1-2 dust particles escape and I have 2 tiny bubbles because of it, but the application was easy and with proper cleaning, no bubbles will appear. It includes 4 repositioning stickers, but without instructions, it is not clear how/when to use them.
