I am no longer happy with the iOttie mount I've used for the last few years, because it doesn't hold the phone well enough. The JB 7 slides out, since it's so slippery, and the side springs are weaker than they used to be. With the leather case on my previous iPhone, there was enough inherent grip, but not with the slippery jet black. So I am looking for a windshield suction mount, without a bottom ledge, that won't scratch the phone. Any suggestions?
