While the product seems to be of good quality, the installation is not easy.
Personally, even though I applied the protective stickers as best as I could, in the end, glue got into the phone's speaker, got polymerized with the UV lights, resulting in the caller not being heard and requiring a replacement of the speaker... with the prerequisite of removing the tempered glass.

While it states that there is an installation tray included in the package, there was no such material, making the installation difficult. Additionally, it does not have a tape to indicate if the package has been opened. The logic suggests that the package has been opened and the installation tray has been removed. It has also been mentioned in another comment that it did not include the installation tray. It's a shame, as it is a serious requirement to choose this particular glass...

To the credit of the store where I purchased the product (Kooqie), I have to mention that the responsible person of the online store contacted me via email, very politely, and explained in detail what's going on with this specific product.
The installation tray is only available for certain device models from the company. Unfortunately, it does not exist for mine (Xiaomi Note 10).
The glass is worth its money, it just requires great attention for proper placement! Pay close attention to whether the cameras protrude on the back of the device, as this results in the phone not aligning properly on the table, causing the adhesive to slide off the screen

It looks like a very good screen protector, it had instructions inside that helped, I think there is a lot of liquid, I accidentally spilled a little bit and it overflowed on the edges. I wiped it immediately so that it wouldn't dry and the buttons wouldn't stick. 4 stars because the box didn't have any sealing tape, so I don't know if it has been opened or not, and the instructions indicated a frame that goes on the phone for easier and more stable placement of the screen protector, which made it a bit difficult for me to align it perfectly straight, and there is a small imperfection at the bottom that has a bit of air.
