With the Fitbit Charge 2, there’s a wealth of features, interchangeable bands, a larger screen and new data tracking with VO2 Max. The size of the display on the Charge 2 is right, and it sits better on the wrist, which is a relief. The overall design is pleasing. This fitness tracker also features workout pause, viewable heart rate zones, new clock faces and vibration support for Fitbit’s guided breathing. It is only available in the US and few selected market, and the Shop2Ship tax-free price starts at $150 while Shop2Ship international shipping starts at $24 to worldwide destinations.
