Customer Ratings & Reviews

Both my fiance and I have recently purchased Flex's, along with the Aria Wi-Fi scale to go with it. Between that and tracking my calories (although I use MyFitnessPal instead of Fitbits' database for that, but they are able to sync together which is great), it gives me a wealth of info about my daily diet and progress. The Sleep tracker has been a surprise highlight feature, as I've found I care more about how much I'm getting a night and have improved my sleeping habits since purchasing the fitbit. The only issues I've had is it occasionally has problems syncing with my Galaxy S5 over bluetooth and I have to try it several times to work, and I've found the wrist placement isn't effective for activities such as cycling, mowing the lawn, or anything where you're hands are stationary. This can be remedied by just putting it in your pocket during that time, however.

I love the flex! I had a jawbone at first but it was a lot bigger and not able to change bands. I like everything about it.

Great product, too bad it does not count how many flights of stairs you take

This is a great steps tracker - but I think calling it an activity tracker is a bit of a stretch (the same can be said for any product in this category). I think the main measure of activity would be your heart rate but it looks like you have to pick up a 'smart' watch to do that these days. The software is good for tracking steps, sleep 'activity' (if you move around a lot when you're sleeping), and logging food and water intake (it's all manual but you can set goals) but I'm not sure how the software calculates how many calories you should be eating to reach a particular goal (most likely based on a generic calculation based on your height and weight - and ignoring body fat %). It's better than many products in it's category and the band is comfortable but I don't like the fastener (it comes with a small & large band so should fit most any adults wrist).

Fitbit Flex is a great, unobtrusive way to track your fitness. Once you sync it up with your phone you can get up to the minute info on steps taken, distance traveled, calories burned, and active minutes. The Fitbit will even track your sleep if you wear it to bed. I would definitely recommend this to my friends!

Does a very good job of tracking steps and sleep patterns.

I put my Fitbit on first thing in the morning . I charge it every evening. It motivates me to walk extra steps each day.

This is a good item if interesting in keeping up with your daily "Exercise".

This is a very basic start to tracking your activity. I have found it to actually be more motivational than I expected.

Much better than a clip on pedometer. With this on wrist, it is difficult to lose, like a clip on. You can wear it 24/7. Resets automatically at midnight, no need to remember to do it manually. I have been using 3 weeks and seems accurate. Like how I can compare my progress with others using a FitBit product. Brings out the competitive edge!

Really enjoy the Fitbit tracker & wristband. It's fun to see your progress.

Does the job and is fun to track your progress daily

This is a great product, easy to use and synced with my fitness pal really well. Keeps track of all of my steps and sleep quality which is great to know. It is conservative on calories burned vs. putting your exercise into the app but I still like it because it is helping me to track it all and I am losing weight and feeling much healthier!!

I really like this Fitbit - Flex. All I want is to track my steps and I like that the design is simple (which is what I was looking for) because I don't want a watch but it syncs up to my iPhone with the Fitbit app and also my computer. I highly recommend this product if all you want to do is track your steps.

This product gives me information that is helpful with my daily workout

Bought as a gift. Getting set up was the hardest part. She is happy with it.

I love my Fitbit! I read some reviews where folks had trouble with the band breaking, I haven't had an issue. I wear it all the time, in the shower, at the beach, in the pool, and have had no issues. I only take it off to charge it. I really like the color too. Best Buy was the only place that carried this color. Very happy with it.

It has nice feature which I'm still learning to use. It was a good purchase.

After using and loosing two Fitbit One's, I decided to go with the Flex and I'm so glad I did. It's water resistant, so you can keep it on while in the shower or swimming, and I only take it off when I need to recharge it. Occasionally, it does not respond with the taps needed to see your progress. But, that's really few and far between.

It keeps track of so many different things. I log my exercise and sleep with it. I wish it were more user friendly for logging calories, but I use My Fitness Pal, on my iPhone for food intake. If they ever get that going, it would be a solid 5 stars!
