    The band itself seems abrasive and almost impossible to get comfortable. The unit itself does a horrible job tracking activities. I can be doing whole workouts and it doesn't register a thing. With how many new companies are producing these for much better prices I wish I would have waited...

    It took so long to come out with the Flex that I figured it would have more features than the Fitbit One but it has fewer features. I was very disappointed with this product. It does not track your stair climbing at all. You can only see approximately what Percent you are of your daily goal - not exactly how many steps. I'm not really sure why anyone would want this product. I ended up trading it back in for another Fitbit One and I am very happy that I did. I will never recommend this to anyone. But I will recommend the One.
