    The fitbit flex is great. It's very light, so I barely even notice it on my wrist anymore. All my tests have show it to be very accurate. It's been a great tool to help maintain a certain level of activity throughout the day.

    I don't even realize I'm wearing it. The charge lasts 3-5 days depending on the amount of steps.

    Really like this product as a pedometer and sleep tracker. I bought a first one at best buy and after about 4 months, it stopped working one day. I took it back to best buy and they were able to look up my purchase on my best buy card and exchanged it completely free of charge. I take this product off to shower as I do not trust the "water resistant" claim. Sometimes it even gets too wet when I sweat during a workout -- so be careful around any moisture or liquids. Overall, a good product.

    Great product, really don't need to know my heart rate. I was looking at some other products but I can go a week without thinking of a charge. Forget it's on and get in the shower no problem..... The next question would you recommend to a friend? Yes, In fact I bought my wife one to.
