Customer Ratings & Reviews

I recently purchased the FitBit Flex to help motivate me to get more active. I am not only able to see how many steps/miles I have done for the day, I can easily input all of my meals and snacks to help keep track of my calorie intake. It definitely makes you more conscious about what you're eating. The only thing I wish the app had was more options for tracking your exercise. For example, I do Jillian Michaels workouts daily, but there is no option for that so I have to choose the closest thing to it. Doing that, though, leaves you to figure out the correct calorie burn-off.

Device works well and tracks my steps fairly accurately. It is very nice to track and record progress each day as well as have a weekly summary. I love that it's waterproof (I essentially don't take it off except to charge battery) and wirelessly syncs with my iPhone App. Sleep tracking is helpful and cool but not extremely useful. Alarm clock feature is great and I use it often. Would be nice to have an alarm based on sleep state like Jawbone. Battery life is very good but device is a pain to charge as you have to remove from wrist, take out of wristband, and use custom charging cable. I also like the look and feel of the wristband. It does get confused by any motion, e.g., riding a bike, mowing lawn on a rider, pushing a cart at store on bumpy floor. All in all, I really like it.

Bought this Fitbit as a gift for my wife. I am on my second Fitbit (Charge HR) and really like the product line. I find the Flex's step tracker to be excellent & as accurate as the best pedometers on the market (like Omron). The sleep tracker on the Flex is a plus, and I've found it to be very accurate for times awake, etc. The Fitbit app for iPhone is outstanding: I use it for tracking food & water consumption and exercise, in addition to steps, miles and sleep. The app syncs often and flawlessly with the Fitbit through a Bluetooth connection. My only complaint with the Flex is the clasp - with vigorous exercise, like cycling, it can come off. That's how I lost my Flex (& upgraded to the HR). Do yourself a favor and buy a pack of those little loops that reinforce the clasp. The pack even comes with a couple repacement clasps. Costs a couple bucks from a certain major internet company. Fitbit would do well to include the loops with the Flex and other clasp type Fitbits.

When I started wearing my Fitbit I started to pay more attention to my calorie intake, and how many steps I should be taking on any given day. I loved how I could compete with my friends, and have a spot to keep track of my weight without having to worry about anyone seeing my numbers.

Got this for my work step tracking and incentives. Was easy to get the Fitbit Flex to install on my phone and establish my account. From there was very easy to link right to my work account for the rewards. High marks on ease of use. First impression for me is that the step count is slightly inflated, but not sure yet.

She's always been a very active woman but she's always wondered how active she was. After getting her this Fit Bit she can't stop moving. She loves how well it keeps up with her steps and her calories expended. Great gift for anyone with is already active or needing a jump.

It's very useful for counting step miles calories burned tracking what you eat is seems to be very durable you can even where it in the shower a charge usually lasts about seven to eight days and only takes a little over two hours to charge completely from a dead battery it's also light weight and it doesn't burn allot of battery life being connected to blue tooth all day very cool easy to use and easy to operate

Helped me out a lot reaching a step goal I set. Also let me know when I was sleeping well or not. Tough to use when you go for a walk or run with a stroller and it doesn't track much of the actual steps if at all... GPS would be better but oh well. Battery lasts about 3 days in the tracker and charges in a few hours.

i love this Fitbit! It's really comfortable to wear which is a plus for me because I typically don't wear anything on my wrists. I love that it keeps me motivated to get up and be a little more active when I check in to see how many steps I've walked. I also love that it tracks your sleep! Overall great product for a great price!!

very wearable , easy to retrive info , stays charged , syncs easily with iPhone 6 - ipad air

The Fitbit is a great addition to my life. It takes minimal care and helps me to stay on track with not only fitness but also health. I like that I can track how much water I drink and how many calories I eat as well as see how many steps I've taken and how long I've been active. It's a great tool to have in a fitness journey.

I was not sure that I would use this very much so I purchased the lower priced model of all the Fit Bits. It turns out just having this on my wrist reminds me to take extra breaks during the day to get up and walk and encourages a friendly competition between the girlfriend and me. The device itself is great, no issues at all. Battery life is good for about a week between charges. It comes with 2 size bands that have a nice secure clasping feature on them that uses a metal insert not just 100% rubber. I was initially afraid that the rubber would pull on my skin or hair on my wrist but it does not and is very flexible. I would definitely buy this Fit Bit again if I had the chance to do it over.

I had a Nike FuelBand for over a year. I loved it, but I looked into the FitBit Flex because I was interested in tracking sleep. I must say I am very impressed with its accuracy and all that it can do! I love the fact that it tracks the quality of my sleep and it integrates so well with MyFitnessPal. If you are looking for something to tie your habits and your fitness motivation together, a FitBit Flex is absolutely the way to go! It honestly was worth every penny! The only thing I don't like, is that the lighter colors of the FitBit tend to wear out on the sides and look "dirty". I've tried everything to remove it, but I just bought extra bands and wear the black or dark blue bands for everyday and wear the others ones occasionally and never everyday.

I think the Fitbit flex costs too much for why you get. It would be nice if it had a watch on it. There are no directions on how to use it or what the different lights mean.Overall it has helped motivate me to be more active and it does what it advertises it will do, but I were to do it again, I wouldn't pay $100 for it.

I wanted a simple activity tracker, and I got it with the Fitbit Flex. It automatically counts the number of steps I take, and tracks my sleep patterns. Although it doesn't "understand" things like yoga or a stationary bike as exercise, I can add those manually; I can also track my water and calorie intake manually too. It doesn't have a watch built-in (it wasn't worth it to me to pay the extra $50 for the Force, which has since been recalled), so I have to wear a watch as well. Manually adding activities, food, and drink is cumbersome, so I rarely do it. And the display is just dots, which can be a little confusing at first. But it is handy just to have a simple reminder about how many steps I've taken in a day.

On the whole, it's a decent product that was ranked higher than any other related products at the time of purchase. It's comfortable, keeps a great charge, fairly easy to use, and the soft vibrate alarm is a nice touch. It's also waterproof. Only downside was that it was not terribly accurate in counting steps and there wasn't a watch feature. They released the new FitBit Force which supposedly improves on the accuracy and has a watch feature (which is great considering you wear this around the wrist.) I've returned the Flex and will be picking up a Force as soon as one is at a local BB.

Didn't know how many steps I go in a day!! Awarded a "wooden shoe" already! Easy to read the results on my cell phone. Encourages good measure of activity. Also, use a CPAP & it gives me a review if my sleep pattern. I am an "elder" citizen, The Fitbit is not only for the young at heart! All age groups benefit! Our whole family sport a Fitbit now. What a contest to be in. Thank you, Would highly recommend.

This is my second fitness band, I previously used the Nike Fuelband. I have to say that I prefer the Flex over the Fuelband. Here are some of the reasons: It is more comfortable to wear because it has multiple band settings. It is durable (but does show a little wear). However, you can get new bands and different colors, so that is nice. The Flex works with both Android (phones with Bluetooth LE only) and iOS. Really like that there is an Android app as Nike has shunned the Android community with no app. The accompanying apps on both mobile OS are nice. You capture miles, steps, calories, and more. The apps also allow you to capture food eaten, activities done, water consumed, and more. That is entered via the apps separate from the Flex itself. While I know the device is not completely accurate with steps and miles (just like the Fuelband), what you can do is use it as a gauge to know how active or inactive you are each day. The Fitbit's that clip to your belt are probably more accurate, but I don't want to deal those and people lose those a lot. One more cool feature that I really like is the sleep tracking. It does an awesome job of telling you how efficient your sleep is, how often you wake up, and how much sleep you get. The Flex also comes with a syncing dongle that can be used via PC, it charges in around 3 hours...which is decent. I find myself charging every 5-6 days. The one thing missing that I wish the Flex did have was a display that showed the time. I really liked that about my Fuelband. However, that is something I can live without. Definitely would recommend this if interested in a Fitness tracking device.

Some interesting & useful info (ex. sleep patterns), and better but not flawless at tracking steps than anything else I've used. But with this price point, I'm not sure it satisfies my personal 'value per $ cost' standards. Got this as a gift and use it every day ..... but not sure if I would purchase it for myself.

I love my Fit Bit Flex. Checked the Nike Fuelband also but love this one so much more. It synchs to your phone. Very easy to wear and not very obvious. Just looks like a bracelet. Shows calories burned, steps walked and monitors sleep. It is a little off with calorie count since you wear on your wrist and several movements of your wrist will record as steps. But I'm aware enough to know how I'm doing. LOVE it....LOVE it...LOVE it. Surprising my husband with one for our anniversary.
