NIKE FUEL BAND ???

As a motivational tool I think it's great but you won't get hard data out of it since it is only tracking the movement of your arm. The fuel number does seem to do a good job providing a "score" that my wife and I can compete on an even level. For example on our last walk I burned exactly twice as many calories as she did because of our size difference but we both earned about the same number of fuel points.

So have you used it, do you like it?
