I will say one thing though. I like the feel of Apple's 6+ Silicone case a heck of a lot better than the 7+ silicone case. the 6+ one was much grippier in the hand. The 7+ seems more likely to slip out of your hand. I guess I will need to find a different case this time around.
are you concerned about the open bottom of the official apple case? i dont know if you got the jet black or matte black but that unprotected open bottom of the apple case is a concern
