Love the design/concept but they need to find a way to shave off some of the width! It appears to be to wide, especially on the bike video where the rider pulls it out of the holster.
Also, I really like the way the headphone port is accessed and cant really tell from the videos if the lightning access is a rubber flap or not but i hate rubber flaps that you have to fight with to stay open.
I really like the Lifeproof lightning access method on their case which is a hinged door! Snap it open, snap it shut.
Also, there has been talk about the mute switch being accidentally switched on/off in your pocket on their previous 4s cases. I could not live with that.
