    I love the flex. It's lightweight and comfortable to wear. The charge lasts about 3-4 days.

    Fitbit has helped me breakthrough my weight loss plateau level that I have don't before. Having an activity tracker to measure calorie burn is essential to knowing your calories in vs out. Fitbit also integrates well with Myfitnesspal app so tracking calorie intake is a breeze. I recommend fitbit over the jawbone UP, because fitbit uses low energy Bluetooth for syncing to your phone. The UP requires a wire for syncing.

    Okay Item, but Not Accurate

    I didn't care for it being on my wrist. It was something that bothered me so if I were to go Fit Bit again, it would be one that clips to my clothes or sits in my pocket. I am a blogger and an office manager. Most of my time is spent on the computer tying. Even on my non-dominant hand (that doesn't move much aside from my fingers) it would still track "steps" even though I was sitting. I noticed the same inaccuracy when in sleep mode. Any slight movement made the tracker count a "step". I liked that I could track everything between the tracker and the app including my food intake. I liked that it could track my sleep pattern. Overall, this particular FitBit was not for me, but I would get a different style.
