The listing, Used BodyMedia arm Band has ended.
this is a body media band. I only had mine for like three months and stopped using it cause the trial was over. Any USB connector will work with it for your computer. It will track all your steps hours slept calories burned and everything once you get the going with the progam and so forth. i paid about three hundred dollars for it when i was on Jenny Craig. Any questions i will try to answer asap. thank you
