Very good discreet protection, comfortable and efficient

The principle:
Unlike screen protective films, this tempered glass protective glass is there to protect your screen without degrading or user comfort (by its matter) nor visibility with an anti-scratch (which is the point low standard protective films).

The reality: evaluation after 2 weeks of use:

Simple and effective packaging, glass well protected during transport, everything is there. The window is quite simple to install properly (without bubbles or Décallage) which is a big plus, but however we regret the lack of operating instructions in the box (unlike some competing models).
The glass: very very scratch resistant: tested with keys, a knife by pressing firmly on it and put in the pocket with my iphone without protection and no real visible gene: microscratches are present but we see them only reflections light when seeking them. Level shock I have not had the opportunity to test since I have not dropped my iphone during my 15 days of testing.
The thickness is soon forgotten (just under 0.3 mm) although we feel the difference in the home button but nothing annoying though.

CONCLUSION:
Very good protection that I recommend to all who wish to protect their screen without deadlock on touch glass and anti-scratch treatment. Here we have a feel similar to the iPhone's screen while feeling the safety device.

Make the leap, I recommend !!
