    Great to track your steps, sleep and intake

    You never realize how much you actually walk until you monitor your steps. It is also able to track your fluid intake (manually), and your food calorie count (manually), and your sleep (manually enter and exit sleep mode). Unfortunately this model cannot track stair climbs. There is a scale that can automatically recognize you and enter your weight wirelessly by just stepping on the scale. I plan to get the scale next. Wrist band is light and I forget I have it on. Two bands are included in the box, each is adjustable to a great extent, it will fit most people.

    Replacement for the FitBit Force

    It is super easy to use and I find huge value in a step tracker that is based on the wrist rather than the waistband. I love the clear look of their dashboard (on smartphones and online) and I love the leaderboard with friends. It is motivational to get a FitBit message from a friend or simply a "cheer". A healthy lifestyle that's supported by my community/network of FitBit friends is great. I love the ability to track my sleep patterns and that I can swap out the bands. However, I can't help but compare it to the FitBit Force which I had to return as a result of their recall and the rash I got from it. I miss the watch feature and the ability to view the number of steps at a glance. I do love so many other features offered by FitBit that I stayed with the company.

    I purchased the fitbit -flex to help me with my weight loss program. I really like that it keeps up with almost everything steps, calories, water. Just wish it had the heart rate feature. My daughters that live out of the area purchased one too, which makes it fun because we can view each others steps, which keeps us motivated.

    The fit bit is lightweight and comfortable even while sleeping. I received the bonus bands when I made my purchase, which is great for color coding with your outfits. Once I realized I needed to download the instructions syncing my tablet with the fit bit was easy. I enjoy receiving motivational emails on reaching a certain goal or letting me know I am on my way to achieving one. The customer service was quick to respond to a question I had through the web site, no phone number to call. Battery life is about one week and its quick to recharge.

    I really love this product. Easy to use and easy tracking. It wouldn't charge but just cleaning the connections and having no issues now. One negative thing. The band look dirty fast and even though I scrub it, band it still looks dirty. I wish the band was a bit more attractive this is okay to wear for working out but it would be nice to have more of a in store choice of bands. Overall I give this an A

    Synced with your phone, this is a great product to help keep track of your eating and exersicing habits. The device really keeps you active and motivated to stay active. I love that you can change out the color of the band (sold separately) too! I love this product!

    Popular Fitness Band

    The FitBit is one of the most popular units on the market today. The box comes with two bands, a small and a large. Would have preferred two of the same size but was able to trade with someone else. Counts steps, has an alarm function and a feature I really like is the sleep monitor that let's you know when you are restless or awake during your sleep cycle. Band is comfortable and waterproof. The unit recharges in minutes and lasts about three days before needing to be recharged. Can be linked to Weight Watchers app.

    Didn't really think I would love it, but I do! I love linking this up to MyFitnessPal to keep track of my calories burned, etc.... I didn't expect to love the Sleep Pattern tracking. Because of it, I am trying to get at least 8 hours of sleep during the week and I am succeeding! Tracking my steps is fantastic and it also keeps track of my steps on the treadmill, whether I'm walking or running. Overall, great product!

    I like the flex and what it does. But I have a hard time getting the band clasped, it is very stiff. I am a 'senior citizen' and there are times when I can hardly push the clasp into the little holes. But I persevere and get it done. I like the challenge it gives me to move through the day and get the exercise I need.

    I love my Fitbit flex. It's the perfect companion with my wellness plan. I like how you can track sleep with it too. The description was perfect. The features of the flex are exactly as described. The battery life isn't too bad either. It's lasted me about 5 days without a charge. The sync with my iPhone is probably the best thing. They have a wide selection of foods when adding your caloric intake. I also like how it keeps me motivated by reaching goals etc. Overall a great purchase for the price.

    I love the color I bought (Tiffany Blue). For the setup I had to watch a youtube video because the instructions weren't clear for me. I charged the device and set the alarm. Alarm is silent but wakes you up with the vibration. Alarm doesn't disturb like my iphone alarm does. Steps are tracked online or in App and can work along with others in set up. I love my Fitbit and it sends notifications/motivations during the day to my phone. I don't think I need the more advanced one I'm happy with this one.

    The Fitbit Flex is a reliable, easy to use activity tracker. I especially like the informative app which is available for download to most mobile devices. Additionally the Fitbit flex can be sycned with other fitness, nutrition and wellness apps if you are currently using an online tracking app. Tracking Sleep takes a few additional steps, but the information is definitely worth it.

    The band is comfortable and light weight considering the material it is made of. I usually sleep with it on except when I charge it over night. I like that I can wear it in the shower and wash the skin oil off. I have been motivated by the challenges I received and I am delighted that I have met and exceeded my challengers!!

    I've been dieting my entire life. This little bracelet makes it so much easier. Counts your steps, calories eaten, calories burned, foods eaten.Tracks carbs, sodium levels, proteins, fats etc. surprising information about foods you eat. Only problem I've encountered is "Fitbit" seems to have a lot of computer outages. Sometimes it takes a really long time to sync your info.

    I love my Fitbit!! Keeps track of my steps & has an alert that I can set to get me up or remind me of something. It also plays a little light show & vibrates once my step goal has been met. The app that its connected with is cool too. Keeps track of my water & calories & allows me to set goals for how much weight I want to loose & in how long. FitBit is the best thing ever invented!!!

    I really like how this will track your sleep. It also makes me want to walk more to reach my daily goal. You can also add what you have been eating and your water intake. It definitely makes you more aware of the amount of activity you do in a day. The only thing I wish I could find are more bands that are dressy/formal and affordable but hopefully that will come out soon.
