It is vfm for consumable, but that's it... the problem is that you need to buy 5-6 in order to have because when you need to change it almost always when you remove the protective membrane it has dust particles on the supposedly clean glass so it leaves an air bubble on the phone. The other problem is that it is a bit reflective so it glares. For the money I paid I don't complain... however, 2 times I changed the glass, I consumed not 2 but 4 glasses... and I never had a perfect result, it always had dust particles on the glass so it left a smudge or 2 smudges. These are on the new glass, not on the phone - the phone is spotless. And you can't clean it because it has the adhesive and then everything sticks to the adhesive, so you throw it away.

It was never installed because it wouldn't come off the protective film. After many hours of trying to remove it, it broke into many pieces and still wouldn't come off

Terrible application, it holds bubbles due to the fact that it is crooked all over the glass, resulting in air being trapped underneath. Black carpet, probably why it is priced like that
