Rated 1 out of 5 by Do your research Wish I had. This took my husband almost an hour to setup on my computer. Then it took him several minutes to close the "clasp" as it was too difficult for me. I can do it now but I need a pliers to close it. If I want to know my status I need to go to my phone or computer. This may work for some but I wish I had returned this. 12/11/2014
Rated 3 out of 5 by Glorified pedometer I wish I would have done a little bit more research. Really, all this is, is a pedometer. The fit bit app syncs everything but there are free apps you could input the data to and have it all there for you since you still have to go to the fit bit ap to log food and water. Not at all what I expected. 12/12/2014
Rated 3 out of 5 by Battery life I love the product when it works. My biggest complaint is battery life. I have had the product for less than 2 weeks and my battery life is less than 12 hours. Hard to track your fitness when it's on the charger most of the time 12/08/2014
