I have an iPhone 5. They sent me the Tune Belt to use WITH my otterbox (protective case) as I said I didn't want to have to take it out each time (Model AB84). I really liked the way you could see and still USE the touch screen through the Tune Belt. The first thing I noticed about the Tune Belt when I put it on was how firmly it held in place. There's nothing worse than something slipping around when you're trying to run. Listen, I have enough of a hard time trying to keep my pants from falling down, I don't need to worry about my iPhone carrying case slipping around everywhere too. That was NOT a problem. It stayed firmly in place and I barely noticed it.
