Three stars because it comes off relatively early, in about a month, so if you don't lose it, it will be useless because it doesn't stick.

This specific glass protector is indeed protective, but it does not fit properly on the mi band 6 as it claims. It might only be suitable for the 5.

I put it on my own and it applied nicely. The truth is that I couldn't manage to put a crystal on my phone the way we usually do. It created bubbles and wouldn't go away no matter what. I took it off and put it back on, and on the third try with a different method, it went on smoothly and correctly. Despite removing it twice, it has stuck perfectly and hasn't come off for at least 2 weeks now. If something catches my attention, I will mention it. It applies well, doesn't affect the screen or its use, and hasn't scratched so far. They say it's not as scratch-resistant as they claim. At least it will protect the watch itself, and if it gets excessive, we can replace it again.

I made a video on YouTube with the Mi band 6 and also placed this specific crystal. [YouTube link]

I also put a second one on a watch with a quite scratched screen and there was improvement. Watch the video with the installation and the result here: [YouTube link]

It gave me quite a hard time during installation, and I couldn't manage to remove the 2 mediocre bubbles that formed.
It definitely doesn't have the "Surface Hardness 9H" that it claims, as some sellers mention 7H.
Regarding protection/durability, I can't have an opinion since it hasn't even been 24 hours yet. I will update the comment with more information after a reasonable period of time.

After 5 months, I have to say that it came off. Overall, it was not a good purchase

I do not usually make negative reviews, but I was a little disappointed with the product... Firstly, it is definitely not 9H in terms of durability... I would say not even 5H... On the first impact, due to my work, it got its first scratch, and on the second day of purchase, it got another one. With 9H, theoretically, it should only scratch with a diamond... Of course, I never believed that these scales on protective glass are 100% accurate, but it got its first scratch on iron without any angle... Since then, it has become a mess with other impacts. The application was not that easy either, as it left a bubble inside, which eventually came off with a little effort and pressure from my nail... It gets two stars because, in the end, it protected my screen, but due to the scratches, it is no longer as clear, and I have to buy another one that can withstand more.

It simply didn't stick to the screen easily, no matter what I did, I read the instructions as always but it still slipped.

IT CAN WITHSTAND WOOD.

1 month in my possession with daily hits. I am a furniture assembler and if I hadn't bought it now, the band wouldn't be worn from scratches.

Only two hits left marks that I thought would have broken the watch in general (without exaggeration).

For its application, I put it on and took it off a couple of times because I didn't put it on exactly and it created bubbles. A couple of small bubbles that didn't go away when I pressed it with my nail (towards the edge, to let the air out) disappeared by themselves until the next morning.

I don't know if I was lucky, but because I will definitely buy it again, I will inform

It creates two huge bubbles that obstruct visibility, even though I followed all the instructions for application.

Tragic build quality, it took me a long time to manage to apply it to the screen without any bubbles. And when I finally did, it completely came off after 10 minutes. Money wasted

It went in easily, it is the right size but after a few hours it starts to come off. I don't know how long it will last...

It lasted only a few hours... Then it came off, fell down, got filled with dust, and became useless... The most wasted money I have ever spent... and it looks like a quality product
