You need to clean it very well with the wet wipes (which come with the kit, in general it has everything you will need so don't buy anything extra) and then dry it in order for it to fit well. If you put it on crooked, don't bother trying to peel it off, a gap will be created that won't be visible and the phone will press buttons on its own. It's both durable and not, because after three months it broke, but to be fair it was a really bad fall and it landed on a corner, but the screen wasn't damaged at all, so it served its purpose, I guess.

In the year 2025-2026, it's a bit difficult after all to find the PERFECT tempered glass for your device... I tried several, paid quite a bit, and this is the best I've put on this particular device, poco f7 5g.
Perfect fit without any distortion of the image or handling at all.
It's important to apply it carefully and center it, especially if the protective case has a recess towards the screen.
I hope I helped

Perfect glass, it is hard, it looks like there is no glass at all and the fingerprint works exactly the same as it did without the glass, it just doesn't stick very strongly to the phone and also a bit of lint got stuck inside but the good thing is that it comes with two so if the first one doesn't go on well you can use the other one

It is a very good and high-quality glass, offering protection without losing anything in terms of screen resolution or fingerprint.

Very good glass and easy to apply.
If a bubble appears somewhere (due to moisture or air), just gently push it with a card, or with the cloth and your finger, so that it moves towards the edge and comes out.
In some cases, you may need to slightly lift the glass to let the air out.

The fingerprint works just fine.
It's a good idea, once you place the glass, to re-register your fingerprint for better response.
