Initially, well then no longer.

Have this glass mitlerweile for about 3 months. (I want to say before that, I had two of these glasses have respectively)
The first glass has held about a month. Then it became brittle in a corner and the individual layers separated.
Got the customer service a replacement glass. This resulted in a Green instead blue packaging. This I have now still in use, however, the highlight of the product description does not really agree.

The "anti-fingerprint" does not really work is precisely the same as in a film.
A major reason for me was that it should be extremely hard and therefore no scratches are formed. It is true also partially on display no scratches come but I have a few scratches on the glass. Although not as many as possible on a protective film formed but I've also 10 paid for the glass.

The scratch or crack has now severed the glass or torn. Unfortunately, I must dispose of it now ..

But applying That was very simple, no bubbles or the like simply forking and it attaches itself to its own. Perfect.
I would order at the front and a rear, as these more easily scratched than the display.
