Good shell but ...!

- The plastic of the shell that I found slightly low end and there comes a time when I sweat hand console slides slightly slipped from my hands. It would have been better to put an anti-perspirant or anti-slip coating.

- The back cover moves slightly, even though I screwed correctly. I tried to remove it, twist it a little and give it but nothing changes. It's not SUPER annoying but it gives the impression of a defect. Maybe is it just bad luck. I have not had the sense to complain to amazon when I bought it but if you happen the same please. Otherwise aesthetically nothing to say, beautiful.
