    Cannot use the food contents. Does not have calories for unpackaged or unprocessed foods ie.. 2 cups cooked broccoli without a brand name. 2 c salad made at home.... Otherwise, it is a good learning tool about how my body functions and a good sleep tracker.

    I purchased this Fitbit to help me reach my weight goal. It has done everything I wanted it to. The app that syncs with the wristband is flawless. I can keep track of my calorie intake vs my calorie burn. I can also track my sleep and know if I am restless or relaxed.

    I was so excited to get the Fitbit for my birthday, as I am on a diet/exercise plan, and the tracker and its associated app make keeping up with calories, exercise, weight, even sleep patterns very simple! I have two complaints: one is that the light, teal colored band turned a dingy color after wearing for just one week. The second gripe is that I wore the band all day yesterday, and for whatever reason, it logged only 50 steps all day, despite having a full charge on the battery. I have had it for a month, and this is the first time i've noticed it was WAY off on measurements. Hopefully this product is not failing after only one month's use, because I really like it! The web and iPhone apps are easy to use and great sources for tracking your diet and exercise habits. I have never used a similar product, but have read reviews on other brands, and I'd say this one has to be one of the better ones on the market.

    We purchased the Fitbit tracker as a gift for my very athletic Granddaughter and she loves it. It was one of her favorite Christmas Gifts. It was easy to set up and get started using right out of the box. She has enjoyed using it and competes with her own record daily. It has given her a goal to reach each day and has been a positive experience.

    I LOVE THIS LITTLE DEVICE, GOT ONE FOR MY GIRLFRIEND AND MYSELF... AND IT'S VERY DURABLE. LOVE HOW IT TRACKS EVERYTHING. MY GIRLFRIEND AND I CHALLENGE EACH OTHER BY SEEING WHO CAN GET THE MOST DAILY STEPS...IT NATURALLY MAKES ME LOOK FOR THE LONGEST WALK BACK TO MY DESK OR MAYBE PARKING FURTHER FROM THE MALL TO HELP GET MORE STEPS...

    I absolutely love my Fitbit. My husband got it for me for Valentine's Day and I have been obsessed with it ever since. Seeing my sleeping patterns has actually improved my sleep and I love being in competitions with my friends and seeing their progress throughout the day!

    I've always been health conscious, but this has made me more. The cool features that lets you not only track your steps, but also my hike's (with GPS) and sleep have made it very useful. I'm also a fan of wearing things on my wrist so it's not too big for that.

    I bought this as a late Christmas gift for my sister so that we could compete as I already had one. She absolutely loves it and was thrilled to discover how many steps she makes in a normal day.

    I bought the Flex because it is small, and I already use a watch. My husband bought the charge, and I am envious. His is more sensitive to his touch, and its features are better. The Flex is good, but I wish I had more of his features on this smaller FitBit.

    Great fitness tracker, but a little inaccurate

    I bought a Flex for myself and a ONE for my wife a few weeks ago. While on vacation, we compared the number of strides and total distance covered to each other and a GPS device. The ONE was more accurate on distance covered (the flex underestimated the distance a little), however, I cared more about the general trends than the absolute numbers. I love the fact the battery lasts a week, and that its water resistant (I've swam laps and routinely shower with mine on). The ONE does have more features (stairs tracking), but I know I would constantly forget to bring it with me, with the Flex, its never off my wrist.

    A friend recommended the Fitbit to me. When Best Buy had it on sale with free shipping it was time to get it. It definitely encourages activity which is recorded and available to compare past and present progress. Friends with Fitbits have challenges you can join to see how you compare to others each day. I'm very happy I purchased it.

    Received my Fitbit as a gift and I love it. It is a great way to track your activity, to set goals and to track calorie intake. I like the friend feature to help to motivate you and keep you on track. I especially like the sleep tracker aspect. Also great is the weekly progress report you get via email to summarize your week's activity.

    It's a great motivator and even I (age 69) learned how to use and charge it. Plus, I accidentally dropped the battery in a sinkfull of water this morning, scooped it out immediately and it's still working. My kids have set up a family challenge, and it's fun to compare and be competitive in a healthy way. I'm very happy that I bought this.

    Purchased this for my teenage daugter who loves it. It's easy to set up and keeps track of your daily activities....not just workouts...Also has an easy to use website that helps verify and helps you to understand how active you actually are on a daily basis.
