I bought my Fitbit Ultra because I recently started a weight loss program and I wanted to be able to track my activity throughout the day. I am very impressed with this product. Throughout the day, the Fitbit tracks my steps, distance, floors climbed, and calories burned as well as assigning me a fitness level that indicates how active I have been in my day. All of these things are synced online and an online record of my activity is stored so that I can look back at my progress. The Fitbit Ultra also acts as a sleep tracker so you wear it at night and it tells you how effectively you slept. This product has given me a whole new insight into the amount of activity that I do in my day and I am very pleased with my purchase.
