When I reviewed the Fitbit Blaze a few months ago, one of my main complaints was its bulky design and the identity crisis over what it actually is: a smartwatch, a sports watch, a fitness tracker, or all of the above to a certain extent. That was never a question with the company's best selling tracker, the Charge HR. From the first look, you knew it was an activity tracker first and foremost, and anything else that it could do was just a bonus feature.

Now the Charge 2 is here to carry the torch. It's an all-around better Charge HR with several significant improvements that nearly put it on the same level as the higher priced Blaze.
