To the window, it must take its time because I think we have the right to a single test. It is best to avoid the off and pick up. The protection covers the entire front panel with holes for the speakers and sensors. The fact that the front camera is covered for me is a good point because it avoids having scratches on camera and thus alter photos.
What I love with this protection is to touch it. I, who was accustomed to the plastic guards, it's great fun to use a smartphone with a window. In addition, the edges are slightly beveled so that it is not aggressive to the touch.
You should know that there is a space between the edges of the phone and protection (less than 1 mm). I think it is for those who have a shell. I have one and suddenly the edges of the shell are glued to the edges of the glass and that's good. It prevents the glass is raised by the shell.
This only been a week that I installed and I have no worries. No bubbles, the glass is not loose, no scratches ...
In short a great purchase that is worth its price and I highly recommend you.
