Protective function -> takes as good as not at all. When falling on the floor, the bottom corners are protected, not at the top, however. Thus one has above quirks in it. After 2 weeks, I have taken out my phone time from the envelope and determine had that have accumulated behind the shell small grains. Now there are lots of little quirks on the back of the phone.
Conclusion -> If you want to have a shell but otherwise not really provides only looks good protection, you can specify the quiet here;)
Addendum:
On my problems with the shell was super received from the manufacturer!
After only half an hour after my review I was told and
a solution to the problem found! -> Therefore, a star more from me;)
Therefore, thumbs up for the service !!!
