How Do I Know If I Have A Fitbit Charge 2 Or 3?

Both the Fitbit Charge 2 and the Fitbit Charge 3 include a screen in the shape of a rectangle and a band that is the same width as the body of the device, but the design of the Fitbit Charge 3 has been improved and perfected. The screen, on the other hand, is a far more noticeable improvement, since the display on the Fitbit Charge 3 is forty percent larger than the one on the Charge 2.
