I have had it on my phone for over 2 years. Before, I used to constantly change protective glass. It has some small scratches but it doesn't bother at all. No comparison to a simple plastic protector.

It seems like a factory screen protector and fits perfectly on the screen without any issues with the case. So far, I haven't encountered any problems. Its durability will be evident over time.

The highest quality I have ever encountered in a mobile phone protective glass.
Nice application method, with a detailed video explanation on the manufacturer's page, easy to center correctly, without making any mistakes.

Poco F3 has perfect application, no problems with touch, and the installation was very easy, I am satisfied

Very easy application with instructions and helpful stickers. The only downside is that it slightly scratches my finger at the edge of the screen, but nothing serious.

Very good tempered glass, tested company 3MK on my other phones as well. The reason I gave it 4 stars is that sometimes the touch seems to stick a little without necessarily being a problem of the tempered glass. I highly recommend the glass, based on general knowledge and experience I can say that the most reliable ones in terms of drops are the ceramic coated tempered glass.

The product is of good quality and I managed to apply it by myself without any bubbles remaining. It is very durable and significantly thinner than equivalent membranes made of pure glass.

I was impressed by how easy it was to install without any air bubbles, etc. And it should be noted that I forgot and took a little while to stick it to the screen after removing the protective film from the membrane, so it definitely collected dust, etc. I think it was the easiest installation I have ever done with perfect results. I will definitely look for this brand in the future.

Very good membrane with perfect application without bubbles, it sticks perfectly. It's like you have nothing on the screen and it has a very good touch feel. It's not glass, it's a good quality membrane.
