Fitbit Charge 2 Activity Tracker In-Depth Review This is truly an in-depth review and compares the Charge 2 with the Garmin Vivosmart HR (sans-GPS) and the Polar A360 (sans-GPS). I'll still probably replace my Fitbit Charge HR with this Charge 2, but only when the wrist band gives out. The Charge 2 does not warrant me throwing out my Charge HR yet. See http://ift.tt/2gqChdO
