I don't know what the tempered glasses of this company say, but this particular product for the cameras is not just unacceptable but completely useless. Don't even bother ordering it... it's a waste of time and effort. They are poorly cut, resulting in some areas not being rounded but sharp corners... As a result, it doesn't properly adhere to the camera lens and is essentially in the air, as it holds air underneath (not in some areas like sometimes happens with tempered glass. It's ALL in the air and you can tell if you press forcefully, then it only appears to adhere to the point of pressure with the camera, this specific product). So it slips and with a simple blow, it doesn't make ANY contact with the camera. It's not an installation issue, I've been doing this for years. It's a product issue. It can't stick as it should and this happens 99.99% due to their poor cutting, which barely removes it from the lens... so little that it can't fit properly, removing the air.

Waiting for the store of purchase to refund the money.
