Fitbit Ultra Wireless Activity Plus Sleep Tracker Blue FB102B

Fitbit makes every step you take a step toward better fitness, even on your busiest days. Fitbit Ultra's super sensitive 3-D motion sensor tracks your day down to details a pedometer can't catch, showing your exact steps taken, calories burned, and distance traveled. The altimeter tracks floors climbed so you can monitor this heart-healthy activity, encouraging you to take the stairs at home or work, or climb a little further on your next hike.
