    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.

    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.
