Garmin Vivofit

Harmon Vivofit tracker. This band tracks your steps, miles walked,calories burned, active calories and time and date. This trackers battery life lasts for a year and is changed out with a battery similar to that of a watch, super simple! Comes with an extra gray band and fits any wrist size! I bought this tracker then my fiancé surprised me with a new one! The battery in it probably has 8 more months of life.
