The fit is very good and all buttons are within easy reach. Even the appearance of the cover is good.
For me it was important to have a shell which is made of soft silicone, but not made of hard plastic and exactly meets the envelope!
But there are two minuses:
1. The edges are quite "sharp", there is of course no danger to slit or hurting your pocket, but by the shell is something bad in his hand.
2. The casing seems somehow thick. Clear a shell needs to protect, but somehow they should also be chic.
All in all a buy recommendation! But no designer piece.
