The Fitbit Charge 2 is a great improvement over the previous model. It is comfortable to wear, has a clear and bright screen, and the navigation is intuitive. The interchangeable straps are a welcome feature but may be overpriced. The Fitbit app integrates well with the watch and the added features, such as vo2 max, are useful. The watch is reliable but may not be as durable as expected. Overall, a good purchase, especially if bought from Amazon.
