The basic idea of having a gadget to track ones sleep, movement and food is great... the scan mode for food items is cool. It probably will never win a design prize but I could live with it's ugliness while it at least worked.
However, my UP-band lasted only two weeks! It never got wet, dropped or otherwise abused... it simply stopped working / charging. No reset helped.
Good idea but lousy product! UP-solutely disappointed!
