How easy installation!

I expected a much thicker glass than that implied the comments.
It is not. Thicker than a standard film but is not a magnifying glass either.
The installation by following the clear instructions in the manual is a real treat.
Clean with the numbered cloth 1
Wipe with cloth numbered 2
Peel the backing off of the glass (there is only one)
Position the glass properly centered.
Press the protective glass on the bottom of the phone (for example)
And miracle! We see the glass be pressed gradually to the top of the screen
No dust, not a bubble!
The touch feeling is the same with or without the protective window.
That's reassuring. I do not test it by dropping my phone to see if he resists shock but I think the quality of the product.
I'll buy another one for my wife.
And I'm going to rush before you take me drive speed.
