Customer Ratings & Reviews

I have now had two of the FitBit Flex models and both had to be returned. The first one was very temperamental about recharging and synching with an iPhone. That one lasted about 4 months before it finally quit charging entirely. It was returned (great service though with Best Buy) and swapped out for a new one. The new one would only hold a charge for about 5 hours- which precluded you from recording your activity for the day (the first one would at least last 4-5 days when it was fully charged). After dealing with that for about a week, the second Flex was returned and exchanged for one of the competitors models with GPS and additional Blue Tooth features, that model has performed flawlessly so far and its charge lasts much longer... but you can’t change bands with that model. The only reason I didn’t give the unit one star is that the features are pretty good. The FitBit “community” is excellent and groups are fun, the information collected is useful, accurate and assists in keeping you active. The community challenges do add a bit of sport to owning one and encourages activity. The optional band colors were nice and it was easy to change the unit from one band to the next depending on what you were wearing. It’s a good idea and keeps you active; just wish both units would have performed as advertised and expected.

Love my fitbit! Works great! Battery life is awesome!

I love my Fitbit even the sleep aspect is AWESOME.

The sleep tracker is my fave feature. Easy to wear

Love my Fitbit!! Very easy to use and works great!

This Fitbit has done its job by making me pay attention to my activity levels throughout the day. Syncs well and has been trouble free.

Purchased for my wife. She likes it because it doesn't look bulky and does a great job of tracking her movement during the day. The iOS app is where Fitbit really shines since you can see your activity and see it over a long period of time.

It easy to use and somewhat comfortable. It goes with me in the pool and the shower without and any problem

Fitbit is fun to use and watch your activity. The sleep tracker does not work well. Have to tap many times to get it to go into sleep mode. We have two in our house and both do the same.

Awesome product very good counts every single step

Keeps you aware of how active you are (or are not)

The Fitbit flex is easy to setup and easy to use!!

Gives me the motivation to keep achieving goals!!!

I got this one for the price, other/more specs came on the more expensive ones.. being a nurse I wanted to keep up with all I was doing and to challenge myself, but it's annoying having to wear this and a watch since it doesn't include both

Great product to keep me motivated and great for tracking sleep habits. Like the ease of use with the phone. Lots of things you can track if you want but you can pick and choose which features you want to use .

Light weight. Good colors to choice from. Go with it

The flex is a great product - I'm very satisfied with it. However, it does have a shortened battery time compared to the FitBit One that I previously had. And it doesn't track stairs (or flights of stairs) but other than that I do love it!

Bought this to track my sleep. Doing a pretty good job at it. Also like the fact that it tracks my steps and how many miles I walk.

This device does a good job at keeping me accountable for how active I am during the day and I check on how close I am to my steps goal by tapping and seeing how many lights are displayed (each light is worth 20% of goal) but to actually sync and view all, calories burned, steps taken, etc. you have to be next to your computer then it will sync automatically. Unlike the Jawbone UP, which you can plug into your iPhone and get your dashboard at anytime. Snaps on securely, don't worry about losing it. In the end, does a decent job of tracking. Little pricey IMO.

Bought 2 of these one for me and one for my wife. They’re amazing if you use them all the time. I couldn’t motivate myself to put it on everyday and challenge myself, but that’s just me. If you’re trying to get in shape and add more steps, then this is perfect. without too many frills.
