Anybody use this thing? I want to get something to kinda make my running feel like more of a accomplishment, and let me track my progress better. Ive been working out for the past month to get into better shape for the Army or Navy and Ive really neglected running since I did not have the proper shoes for it. Now I got the proper shoes and they work with the Nike+ thing so I was just looking for some personal insight into it and if its worth it or not. The wristband is like $60 and I dont want to spend the gwap if its not worth it. I already got $200 into the shoes alone.
