    Works well. (however had to return because 1st one was defective). Works great with the app or pc. Fun to challenge yourself and others or taunt your friends. Tells you how active or not active you have been, can count your calories if you plug it into the app. how long you exercise, etc. Helps to keep me active and let me know how far behind I am when I am not meeting my goals.

    I haven't taken Fitbit off, except to shower/wash, since getting it. The activity movement tracker not only helps in meeting exercise goals but it's really great in monitoring sleep. Also the blue tooth and wireless connections allows you to easily interface with the many features you can monitor.

    Got it for my wife. She used it with ease. Software and apps were easy to setup. I say beginner because it is not as feature rich as other models. She now has the fitbit flex HR and likes it a lot better as there are more features. Please remember these are only as helpful as you make them.

    This tracker is easy to wear and helps motivate additional activity. The sleep monitoring function and silent alarm are also great and the app and website provide a lot of great data. Bluetooth sync function pushes this over the top against other similar items.

    I am comfortable that the steps monitor is quite accurate. The sleep monitor gives interesting results, but I am not confident in its accuracy. It showed that I was asleep during periods that I knew that I was still awake; I think that if you are lying still, it assumes that you are asleep.

    Purchased this after my previous fitbit got recalled due to skin irritations. I love fitbit but I miss the display that my force had. But the flex works just as well and it is thinner than the force was which is nice. I hope fitbit works on coming out with a new wristband tracker with a display.

    I got this for my mother for Christmas and she absolutely loves it. her favorite part is that it can suggest that you walk a certain number of steps per day, and tells you how close you are to reaching that goal each day. So she'll walk around the block a couple of times after work if she hasn't me the quota and doing that is great for stress relief and light cardio.

    Very slick and clever product. By simply being worn on the wrist it is able to track steps and activities fairly well. It won't track stationary exercise like an exercise bike, but it does well with walking and running. General activities, housework and such is tracked less accurately, but overall it is a good relative monitor of activity, and better if you manually log in your exercise bike and others things (eg calisthenics). My main gripes are the lack of an alarm to tell you that you have been sitting too long, and the few models of phones supported. The clasp is clumsy, but that's minor. Overall all a good product for its purpose, excellent considering its low cost.

    I heard about this product watching Dr Michael Roizen on TV, he said the magic number is to take 10,000 steps daily to help keep you healthy and you can keep track with the Fitbit. I love this product and the app on my phone keeps me on track for my daily goal. Haven't used the sleep function yet.

    Glorified pedometer

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The phone app is not all that user friendly. It is really difficult to add food and exercise. It doesn't track exercise on the phone app unless I add it manually which is rather confusing to do. I wanted to keep track of my steps, that works wonderfully. One of my friends said her exercise shows up on her computer but not the phone. I have not synced mine to anything but the phone. The sleep feature, you have to remember to tell the app you're sleeping and when you wake up. But it does show how many times and for how long you are restless while you sleep which is interesting. All in all I am satisfied with the pedometer feature, which as my main concern.

    This is my 2nd Fitbit in the last 5 years. I had the original Fitbit and loved it just as much. This time I got the Flex in the band and I like the idea that it's just always on my wrist and I don't have to clip it on to anything. It would be nice to have a bit more stylish bracelet for events where I dress up but other than that I have no complaints and can't say enough great things about it. It is so simple and easy with the syncing. I originally got the Jawbone Up and it was not as simple and accurate as what I find the Fitbit to be. I thought it would be a comparable product but nothing seems to compare with the simplicity in use as the Fitbit. They have a great product that I would definitely recommend! I just went and bought the Fitbit aria scale yesterday so I am excited to get it out of the box and use it to see if it's as great as the other Fitbit products!

    Pros: Tracks my sleep, works great with the FitBit app to track exercise - the app uses GPS from your phone to draw you a map of where you were. Just a few taps let's you know how far you are into your goal for steps for the day. Cons: no clock function so I still need a watch. Band is tricky to get secured but it certainly stays secure so I guess that's a double-edged sword.

    I really love this device. It helps me keep track of my activit, how much fluids I'm getting, and keeps me motivated. It's waterproof, and I love that I can shower and swim with it on. The most amazing feature is the ability to set silent alarms.

    I like this new toy of mine. It does a good job of keeping track of my activity. The nice part is that I can check out how I'm doing on my phone and not just on my computer. I like the silent alarm feature and it's easy to set. The one thing that I'm VERY disappointed about is that it does not track stairs climbed. I climb a lot of stairs every day and I would like to know exactly how often I do it (probably less than I think I'm doing). It seems like this is an important thing to track and another of their products does this. I expected that the newest model would have ALL the bells and whistles. Hopefully they will provide an update to the firmware for this feature.
