I have had it for 1 year and it has fallen several times, but the only thing it has done is a slight scratch on the screen, it is very sturdy.... I followed the following steps as soon as I opened the package:

1. I tried it without removing the plastic film from the screen protector on the phone.
2. When I placed it very carefully on the phone, I cleaned it with a glasses cleaning cloth of my own.
3. Then I pressed it to make sure it sticks well to the phone and left it for 2-3 minutes to settle. After that, I occasionally pressed it during its use for 2-3 days.

I have to say that it is very good and does not affect the use at all

Good, but it does not include a cleaning cloth, a dust absorber, or a dirt and dust removal wipe in the package. If you don't have your own, there is no way to properly place it
