This has put me off this case as well. In the two years I've had my iPhone 5, my Speck Candyshell case has thankfully saved my phone from a number of face-first falls. I'm not sure I could count on this case to do the same, given the minimal lip.
I have the gunmetal and the gold on my space gray 6, I switch back and forth.
My phone tends to fall out of my shirt pocket every so often... It's done it's job. I'm very happy with the protection.
I had a couple of these on my 5 as well... Great case for short money
I had the Smooth Black Spigen Tough Armor case for 5 days and I wasn't happy with it. It's not the same as the iphone 5 case I had.
The top corners kept popping out when I pull 6 out of my pocket and the sides of the case are not that tight as the 5 case was. And there's the lack of lip surrounding the screen. I have Apple Leather Case as temp, it provides more lip than the STA does. Disappointing.
I wound up returning mine due to not liking how it felt in the hand. Just too boxy so I couldn't 1 hand it like with the apple leather case. That and the lack of a lip for a case that claims to be "tough"
