Waste of money, it keeps bubbling from the first moment. A simple gelatin would do a better job.

It does the job just fine... however, it is a thick membrane and not glass... in order to avoid bubbles after installation, as you apply it from one side to the other, press it gently wherever it starts sticking and if any part remains unattached, only peel it off from that side and press it again slowly. In the end, there won't be any left

This particular product is NOT Tempered Glass, but a flexible MEMBRANE.
Unfortunately, I ordered it as Tempered Glass and I had ordered 2 pieces as backup, but it turned out they were not.
Due to its flexibility, during installation, several bubbles are formed that are difficult to remove towards the outer side, and even then, some remained.
Finally, due to the fact that it fits exactly around the perimeter of the watch and because of its flexibility, it is almost certain that it will come off from the edges with everyday use.
Yes, it is economical and according to its flexibility, it will protect the screen from scratches and impacts, but I would not recommend it.

I don't like the quality at all, it also doesn't fit well and it can come off or detach accidentally at any time. I wouldn't recommend it.

It came off on its own after a month of use without the watch getting wet. It protects the watch well, however, the plastic (because it's not glass) scratches easily

It is good, but I got a little tired of trying to place it straight. It protects the screen well from scratches, but it doesn't have protection on the sides. However, I wouldn't wear the watch to work without this glass
