Query: Great Motivation

This is a great product for motivating someone to run. I would suggest getting the shoe pouch to go along with it as well as a case to hold the nano and the receiver at the same time. I would not suggest getting the case with no window as it does not allow you to see the screen of the nano. Nike makes another one with a clear view of the screen for a little more.
