I would venture to say this is so much of a no-brainer that you would have to be little off in the brain to argue otherwise. It's that much of a difference. I just received my Seidio kit after returning the one I bought from HTC. Umm, where do i begin? *CAN USE WITH OR WITHOUT SEIDIO PHONE CASE. I REPEAT, CAN USE WITH OR WITHOUT CASE *Car Charger included *Neck is at least two inches longer than the HTC version *The part that holds the phone rotates 360 degrees *Has a power output *And is CHEAPER, although you have to pay S&H I mean, c'mon? Who here can argue for the official model?
