I have a few grade A fully functional refurbished Fitbit Blaze watches. They are in top condition and work amazingly! This does NOT come with a charger. Some of the features of the Fitbit Blaze are: •See simplified heart rate zones for quickly checking exercise intensity during workouts with PurePulse(TM) continuous, wrist-based heart rate •Use multi-sport tracking to track runs, cardio, cross-training, biking and more. Effortlessly and automatically record other workouts to your dashboard with SmartTrack •Enable connected GPS to map your routes and see run stats like pace and duration on display (when your phone is nearby •Track steps, distance, calories burned, floors climbed and active minutes. Stay connected with call, text & calendar alerts and notifications from your favorite apps like Gmail, Facebook and more (when phone is nearby).Start a FitStar workout on your wrist and get step-by-step instructions and graphics to ensure you complete each move correctly
