    I have the Fitbit charge hr and bought this for my teenaged son. The display consists of a series of flashing dots and you're supposed to know how to interpret the dots. Like morse code. Son hates it. It's for sale now.

    My original Fitbit Flex tracker was lost when one of my cute replacement bands failed and I lost my tracker. SInce there are so many new Fitbit models, I searched Best Buy and found that there was ONE left at my closest store. Needless to say, I snapped it up that day and have been very happy with it.

    I bought this activity tracker for my daughter because she wanted to track her fitness goals and I personally own the same activity tracker myself, so I'm aware of the benefits. It has helped me to keep and exceed my fitness goals and I knew it would do the same for her. Its certainly a worthwhile investment and I look forward to seeing her transformation.

    Since I do both aerobics and Les Mills Bodypump, in addition to a daily walk, I was looking for a product that would track the calories I burned. What I found was just a fancy pedometer. I still had to manually log my exercise. Food must also be logged manually, which I understand, but much of the food I wanted to log was not in the database. Since there are free websites for tracking food, calories and exercise, I felt that the price of this product did not meet my expectations. However, I did like the sleep tracking feature of the Fitbit. It showed a graph of sleep, restlessness and awake times. I also found it easy to wear and easy to recharge.
