    This is my first pedometer. The software is quite sophisticated. Manually entering daily calorie intake, while making one aware of daily nutrition, can be very time consuming.

    This is a must have when you're wanting to workout and control what you do in your daily workout. The goals are exact and easy to customize your personal goals! Love the wake-up function and it really works without disturbing my spouse!

    Average - issues with accuracy in distance, steps

    Putting the fitbit on the first time was terrible. It was nearly impossible to get the band connected. Recommend putting it together before putting it on and then taking it apart and putting it on. Concerned about the continued inaccuracy of steps taken, distance, and active minutes. As compared to my IPOD fitness program and distance measured by vehicle, the FITBIT is off in all 3 categories regularly. Love the sleep monitoring mode and hidden agenda. When this one dies will not purchase another one.

    I like the idea of having something like this to monitor my activity for the day and sleep at night. I couldn't get the band to stay closed so I lost it. The vibration portion wasn't working so I was unable to use that in an attempt to find it. I contacted FitBit and the sent a new unit in a reasonable amount of time. I haven't used the new one yet as I am hoping to be able to trade it for the FitBit Force.

    I'm a soccer referee and bought this to track my running during games. If works great and the step tracker is pretty accurate. It's not perfect, but it works very well.

    If you want to know what your step count is and take advantage of the app related tracking, this is all you need. No bells and whistles, just the lights to quickly let you know how you are doing with your step goal.

    While I love the Fitbit, it was not right for me. I was disappointed in the fact that it does not show your steps. You have to look on your smartphone or computer.

    The Flex comes with very little instruction makes it difficult to set it up. I have to download the Fitbit app and goto Fitbit website to get it going. After playing it a few weeks now, it still does not provide accurate tracking. Everything seems to be guesstimates. It's super easy to sync the Flex to my iPhone 4S with the Fitbit app via Bluetooth - the top reason why I pick it over Up and Fuel. However, even with background syncing and silent alarm turned off, I have to take it off my wrist to charge up twice a week. To make the matter worse, the Fitbit app does not give accurate battery life. It would show half battery before I goto bed, then it would run out of juice in the night. This problem along with lack of auto start sleep tracking mode means you must remember manually tap it into sleep tracking mode or you get no data in the morning. Lastly, although the wrist band is somewhat stylish, it begin to show signs of wear with a week of use. Overall it has a few advantages over its competition, yet still feel like a beta product. Hopefully a new firmware upgrade would add auto start sleepy tracking mode, improve battery life, and provide more accuracy tracking.

    This thing is incredible! You can go places other fitbits wouldn't go! Furthermore they take into account dominant arm movement and I can wave to people and it doesn't count as steps. This has really helped me strive to meet my steps goal!

    The total steps and calories don't match what the treadmill reflects. It doesn't track a stationary bike and add those miles and calories into the total miles and calories

    The product was very helpful in helping me set and reach goals. The wrist strap came undone and fell off twice. The second time I lost it so I only had it for two weeks.

    My wife and I have run these so we can do some challenges with friends. They work well and are relatively inexpensive. FitBit has a lot of interesting things to offer to keep you motivated and their devices work well.

    Love this. Only complaint is that it doesn't count steps when your arm doesn't swing, like when you push a cart around Walmart for an hour. Otherwise great and I love it.

    But not so happy that my band broke only months after purchase. I can still wear it but I'm sure eventually it will all go.

    Definately would buy again. Not 100% accurate but enough to be a guide. If you are looking for tools to help you love a healthier lifestyle this would be a great purchase
