I was under the impression that this was a "glass" screen like the other items from Zagg. This was just some cloth that was wiped over the screen. I don't know how much protection it will offer.
The application was simple and easy. No issues with any features being inaccessible due to screen protector. Doesn’t interfere with the Otterbox case I have. ( the big beefy one.) So far only dropped once but was only from about 1foot so no damage.
Just an absolute piece of shift. And the warranty will not cover anything. If you've seen the movie Tommy Boy, just think of the scene where he talks about warranties being made for pieces of shifts. That's what this is.
