    I've been hooked up to the device for about a month now. And because it's always on me, I can't forget about it. I had originally bought it to lose weight (keep track if everything to help me lose). Well, I have it send all the info to my phone, where in the app I also count calories by plugging in what I eat. The counter for calories burned and steps taken change colors as you get closer to your goals. Turned I to a game for me, pushing me to reach these goals everyday. It's a perfect little motivator (and reminder) to workout or eat a bit healthier.

    It works great and motivates me to work out and move even when I don't want to. The clasp can come undone. Had to order a watch style band to secure it from coming undone.

    IF you need a little push to get you and moving, this is great. It is a mini competition with yourself. Also can link up with friends that have it and get motivated that way as well. The goal is usually 10,000 steps (seems like a lot but is really obtainable) and I try to reach it every day. I definitely walk more than I used to!! Try it!!

    I wear one everyday and bought one for one of my grandchildren. We are ready to improve our health and bodies and Fitbit is a useful tool as a motivator in that regard. Love it.

    I like it, but had to replace less than 1month after purchase as it stopped working. That's why the "keep the receipt" summary.

    Happy Wife

    My wife purchased this after losing her last one. She wears it often & it has been very helpful to her to monitor activities. She even wears it at work. She tries to get 10000 steps in a day & this helps her meet that goal. It works with her IPhone & the map my run app. We also use when bike riding. Can wear it on wrist & clip to shirt or pants. When we are walking distance together we wait for the alert alarm to tell us we have reached our distance goal. We do recommend it & it is easy to set up & use. It charges Via USB cable. Pretty cool device!

    It's a useful tool but deficient in battery life. The clasp is not secure. My son lost his because it came off during the day. Would be better with a display similar to vivofit.

    Great exercise piece. Easy to use and to charge. The only minor issue is when you tap to get in and out of sleep mode, the response is slow. Overall a very good product. It can surprise you to the number of miles and steps in a day.

    My primary goal was to keep track of my steps per day w/o constantly carrying my cellphone. Also the competition of fitbit friends prompts me to push myself to walk more.

    Easy set up with the iPhone. My parents loved these gifts. Fitbit makes other models with more features but the flex works well as a step counter and basic sleep monitor.

    The flex bracelet allows you to stay motivated and on track during your workout or just for everyday tracking. I love the fact you can add friends and make it a little competive!

    It does what it says but I think it might be better to splurge for thenone that monitors heaet rate and etc right away. I bought this for my wife as I use the lesser model that clips to your clothing. There is a setting that you can designate if you are using your dominant hand which makes a huge difference, but I still don't think it is very accurate. This was bought for my wife as I use the lesser model that clips to your clothing. I personally believe mine is much more accurate than the wrist one.
