Customer Ratings & Reviews

Great tracker to help you focus on your health and fitness goals. Lightweight and comfortable to wear. Syncs great with IPhone.

I purchased the fitbit flex to replace the fitbit one and I had good luck with it for about 5 months. I then started having issues with the accuracy of it tracking my steps and sometimes would notice that it would stop responding all together. After a day or so it would start working again. Now it doesn't work at all. I plug it into the charger and it appears to have a full battery but when I disconnect it, the device does not respond. I have contacted Fitbit support who in the past have been wonderful to work with and usually replace the device with no issue. It has been several days but hopefully I will hear back from them soon. I also wish that it displayed total steps and/or time on the wristband.

The Fitbit worked like it was advertised and I was pleased with its function. However, the strap came apart and, consequently, my Fitbit is somewhere in my yard. Lost! If purchased, get something, like an O ring, that will keep it together.

I ordered the "teal" fitbit flex. Online it looked 2-toned, so I ordered it. It is not 2-toned, but instead a solid bright teal/kind of aqua color. I also thought the large band would fit my ankle. Wrong. :( I also found out you can buy an assortment of bands from other sources relatively cheap.

Do I tried the jawbone and I just didn't like it. I gave that away and got the Fitbit because of all the features it has. I was going to get the new Nike Fuelband SE but all the reviews say the Fitbit is much better. After buying, I opened it up, downloaded the app and follow the prompts. Very easy set up. Then after 20 min I check my dashboard and my bday, height, and weight was deleted. I went back in and re-entered the info a second time. Then I noticed that my steps jumped from 129 to 340. This is impossible because I'm on crutches and I haven't even taken 40 steps in the time that I have owned it. Right now I'm giving it a good rating because the features are cool, design, and simplicity is awesome. I'm worried about the tracking now. I'll have to keep an eye on it.

It was working wonderful, it synced it kept track of my steps, it synced with myftiness pal. Then one day the lights were all wonky and it wouldn't charge or sync. It just stopped working after about 3 months.

This thing is magnificent, when wearing on my non-dominant arm, it tracks nearly flawless!! Very comfortable to wear, shower with it, jog with it, left weights with it, spill food on it, I don't give a $#$%* what you do to it, it keeps on working!! Great invention by fitbit, worth the money!!

I purchased one of these for my father and one of the pink ones for my mother. The bands are difficult for many older individuals to fasten themselves (Up by jawbone is a better band for those with limited dexterity). The display on phones for sleep pattern are poor, there were no instructions included with the device, I had to go online to find info to help my parents figure out how to work it, and then with trying to remember to tap repeatedly while watching for certain lights to light up, is just insane. I ended up trashing these and getting them UP 24's Much easier to work with.

It doesn't show the time, so you have to wear a watch in addition to it, and it's not cute. It does count the steps, but it's lacking an idle alert. I have really enjoyed that with my Apple watch because sometimes I get bogged down need to be reminded to get up and move. The band is very hot to wear, so I bought a pendant and wore it around my neck. I ditched it when I got an Apple watch, and I enjoy the way that tracks and the achievements it sends much better.

This is a Great Product, if you're into working out and keeping track of what you do.

Bought the Fitbit for my husband and I so that we can compete with our friends on the challenges. We actually love it! It's helped us stay motivated and we started working out more because of the Fitbit!! Highly recommend! We even bought the Fitbit scale

I purchased my fitbit flex back in January and loved it. After purchasing and raving about my progress to various colleagues - they too purchased varying Fitbit products and we all motivate one another. Sad to say, that the person responsible for at least eight other people's purchase has lost her's. I tried everything in attempt to find my flex, to no avail. I will purchase another tracker but will try to find something that I am less likely to loose. Unfortunately, this was not the first time the clasp on my flex became undone. Buyer beware...Fitbit should strongly consider making a more secure clasp for the flex and maybe even adding a feature similar to the "Find my iPhone" application.

I like the versatility of FitBit flex. The interchangeable bands make fitness fun.

bought this product as a gift over a year ago. Recipient loved it and still using.

This was purchased as a birthday present. Recipient seems very happy with it.

Replacement for older model. Very happy with the way it measures activities.

This one helps a lot to maintain my physic....amazing price as well...worth it.....

I love my Fitbit! I feel absolutely naked and lost if I don't have it on. Easy to charge by plugging in to my computer and I can save money by not buying batteries all the time.

I had the Flex for a few months and the rubber band/ strap started to fall have tiny tears in it. Fitbit customer service sent me a new band right away. Fun little product.

This is a perfect tracker for your basic needs. No bells and whistles, but when linked with a Fitbit Aria scale and the fitness app of your choice (I use LoseIt) it was instrumental in helping me lose 25 pounds in 10 weeks.
