EDIT: I forgot to mention the installation process, I add it here:
The protection comes in a small cardboard sleeve inside is therefore the ExpertShield protection, held by two transparent films denominated "step 1" and "step 2".
Use the cleaning cloth to clean the screen before installation.
Peel then slightly the "step 1" (the "sticky" part), then apply gently on the screen and you must then do well "pressure" to take off the rest of the protective film (to avoid bubbles). Consider using a credit card-like object for your convenience.
Once everything is installed / removed bubbles (those at the ends are quite difficult to remove completly), you must complete the installation by removing a second protective film ("step 2") located on top of the ExpertShield protection.
End of the edit.
This is my first purchase a screen protector, so there is a good chance that my "lack of experience" have contributed to the tedious side of the establishment of such protection.
However there is one thing that must be reported on the installation process of this protection on this smartphone:
The label "Step 1" (and therefore the one through which the plant starts) encourages us to stick the protection starting BAS smartphone (in prennant as a benchmark the microphone hole), and going UP.
But if we hold exactly the protection around the microphone (down so), once you reach the top there is a good chance that the protection overlaps the two holes of the earpiece and the front camera.
So it takes off again and start over (leaving this time a little more room around the microphone down).
I think it would be logical qu'ExpertShield places the label "Step 1" on the other side of protection (TOP side), to incite position taking as repere UP the phone (and thus both ports earphone + front camera).
In the current state of things, leave a little room when you start to put the protection at the bottom of the screen (around the microphone) to avoid having to take off again once all reached the top.
Aside from that, the product is well packed (cleaning cloth to clean before applying the protection) moultes with explanations given on the package, and I STRONGLY recommend to use a credit card to spread like object way of éfficace protection by avoiding bubbles.
This is much less obvious if you only use your fingers to "guide" as you go.
Once installed, protection is forgotten (except for a slight reflection "rainbow" when the screen is off) and does not affect the responsiveness tactile.I
It is still too early to assess its durability (I did not use or apply sander on the screen, as in the demo video of ExpertShield!), But this seems robust.
For now it is a good price / quality ratio
