Customer Ratings & Reviews

Love my fitbit. It's easy to use and compact. I had my first one for 2 years, this purchase was a replacement. Having it keeps me motivated to move.

So far I'm really liking the Fitbit Flex. I haven't experienced any skin irritation and I like that it syncs easily with my calorie counting app on my iPhone. Because it sits on the wrist, it inflates the number of steps you take a day, but any wrist pedometer will do that. If anything changes I'll update my review but so far so good!

I like being able to track my activity, both during the day and night. I can see why I wake up so tired! Wearing it during the day motivated me to walk more. The downside is that it's too easy to lose. It has come off a couple of times when I've been doing physical work. It's too expensive to not have a better way to prevent it from getting lost.

The Flex is great for workouts and sleep analytics, but the battery life slowly depreciates after a few months. Plus the connector got corroded and wouldn't charge anymore.

I love my Flex from the standpoint of how well it tracks. It is very accurate for the job it is designed to do. However, the bands that the Flex is carried around in are JUNK. Both the original band and the small band from my boyfriend's Flex have both snapped at that black window that allows viewing of the dots on the device. I tried to have the original band replaced but its a 20 step process including a photo and the receipt so I gave up when I couldn't find my receipt. So, right now I have two broken bands - they still work but I have to be extremely careful not to lose the Flex. I bought both a Flex for my boyfriend and son and their bands have also snapped. You have to take the Flex out from time to time to charge it and that is when all the bands have broken. VERY BAD design.

I was unsure which item to purchase, but I am very glad that I went with the Fitbit. The only time I take it off is when I shower. I use it with the My Fitness Pal application and it works great. It tracks my calories in vs out, sleep and will track my steps. The Fitbit is a great tool to calculate how many miles you walk/jog/run and your time. It calculates active minutes to get you moving. I found the web page easy to access and simple to navigate. I recommend this to anyone who would like a tighter control on calories in vs calories out.

This item is used all the time. It is easy to work with and the charge lasts a long time.

So I like the design although it's nearly impossible to clasp this thing with one hand and I like the amount of options for your fitness and eating HOWEVER I bought this after my jawbone Up24 broke because of the sleep tracking, I was VERY disappointed. Once in sleep mode if your just holding still reading it tracks you as sleeping making it very inaccurate. My up24 was older and could tell the different between reading and sleeping. Very disappointed in the sleep tracker.

Flex performs as expected and the app is great/very intuitive. The band isn't very sturdy though so be careful.

Works good, comes with 2 bands. App is good. It has a cool competition feature.

I have a Fitbit Charge HR and I still prefer the Fitbit Flex because you can change the bands as well as use it in a sport cuff. I like to use the Charge HR while working out and the fitbit Flex for daily purposes.

I am in love with the fitbit flex. I bought it to help with weight loss I have had it for about a month now and I have lost 8 pounds. My only complaint is the app doesn't have a lot of options for food. I usually use my fitness pal to figure out calories for food then go to the fitbit app and create a new food with the info I got from my fitness pal. Overall I am very happy with my purchase. 4 of my friends have already gotten one for themselves for different reasons. So I obviously would recommend it to family and friends.

I love my Flex. It has kept me motivated and track daily steps, choleric intake, and water intake. The best part about it is the analytics and reports. They are detailed and give me a good understanding of where I'm at as well as how far away I am from my goals. There are also great plug-ins from other apps like My Fitness Pal and Microsoft's Health Vault. It is like a central repository for my health information.

Great job and keeps me active. First one had a faulty charger, and would not sync to the app, but the replacement works perfect. Couldn't be happier.

Fitbit has a lot of great products but this is not one that I would ever choose again. The flex is simple and easy to use. It is easy to understand and the display is minimal. However, it is inferior compared to the other models that were released after the Flex. The only thing that the flex wrist device tells you is how many steps you have walked toward your goal. There are 5 lights. One light = 20% of your goal. That is all the wrist band tells you. You can get more detailed information with the app but it's not convenient. With the Charge model and beyond, you will be able to see a lot more information on your wrist band with barely any more bulk than the Flex. I highly recommend putting a few extra dollars into the Charge or Charge HR. You will not regret it.

Best thing I've done for myself. It pushes me to get the steps in. Doesn't look bulky on my small arm.

This is perfect for what I need. I really wanted something to track my steps and sleep. This does both.

This is a great tracker for someone that is trying to get a jumpstart on a health kick. It tracks your sleep as well as your movement for the day and using the app makes it seem as though you are competing against yourself and even others.

This was the best thing before APPLE and Samsung smart watches.

Really enjoying the Fit, I track my water intake, steps and calories. It makes being healthy a fun game.
