I have been thinking about what I would like to ask my husband for my birthday coming up. The Fitbit Flex is a band that you wear around your wrist to help you become more aware of your daily activites. The Fitbit can detect how many hours you are sleeping peacefully (without being restless), how many steps you take, and how many calories you are burning. All of this information can be monitored on your smartphone. There are a couple of colors to choose from but I think I am going to get the black, since it will be the most versatile. It is a little spendy... $100. What do you think? Does anyone have any opinions about the Fitbit?
