    The tracker is easy to use. It lets you list almost any food you eat easily. The mode to track your run is great to let you know your time and path.

    My FitBit gets me moving

    I've had my FitBit Flex for a few months now, and it really helps remind me to move more. I work from home, so my normal daily steps are very low. The ability to see your friends' weekly average steps helps with motivation via competition. My teal colored band has gotten a little dirty, but I like that there is the option to buy other bands, so my teal one is my "workout" one.

    I love my fit bit flex. It allows me to track my steps, but also does a little prodding to encourage me to achieve 10000 steps a day as a minimum.

    I love this product and am pleased with how well it tracks steps and easily syncs with my phone and computer. It also keeps up with my sleeping cycles and let's me know if I am getting a solid night's rest. Love it!

    I lost my first fitbit & felt "undressed without it! When I purchased the Flex Fitbit, the sales person was extremely helpful for a cllutz when it comes to electronics! He programed my fitbit to my IPhone that was previously established & added the "activity mode". I knew shopping at Best Buy would give me the best service. Thank you
