I bought this to go running. The band is very small, barely fits on my arm. The button area on the front does not match up with my ipod Nano so when it is in the sleeve, i can't switch songs or mess with the volume. I would have to pull the nano out of the sleeve, switch songs, find a good volume, and then put it back into the sleeve. When you pull it out of the sleeve, the headphones often pull out of the bottom. As you can imagine, I found this all out while running on a treadmill and almost killed myself trying to get a song i liked to play at the correct volume. I really thought I was getting a deal because this was a Nike band, but it seems even Nike can put out a turd every now and again. This is fine if you don't need to switch songs or change the volume, and have skinny arms. I guess you get what you pay for, because this was pretty cheap.
