Customer Ratings & Reviews

First one did not hold charge. Had to contact company. Replacement sent immediately and working well. Very happy with it now. First Fit-bit had the same issue.

Everything I expected! Love all the features. Only thing I would change is to get the Charge instead since it'll tell me the time and elimjnate the need for a watch.

I love my fitbit. I have already recommended it to my friends. It keeps me motivated, it's very accurate on my calories, exercise and sleep.

I would definitely recommend this product to everyone, works great, has lots of options, buzzes to let you know you met your goals !!

If you are interested in knowing what you do all day and how it affects your health and fitness you need one of these

I had a Fitbit one and loved it, but have found the convenience of wearing this on my wrist is easier than finding a pocket! I wear mine all the time and it works great. Sad that it doesn't keep track of stairs like the One though!

I love my Fitbit Flex. I always had problems with pedometers but when I got the Fitbit I no longer have to worry about it. I love that you can get different color bands to match your outfit. I wouldn't give it up for anything else.

Other than missing Sleep Tracking twice, this hasn't let me down. It communicates wirelessly, the battery lasts as long as it says it will. The app could have more foods and exercises but being that it syncs with My Fitness Pal it's not imperative. I would like to get more bands to rotate but no stores have them in stock. Only eBay and Amazon at exorbitant prices. FitBit may not have anticipated the popularity of this product. I love it!!!

This is a great band for my wife, I wish they had more options in pink. Battery life could be better and the sleep tracking is lacking compared to other brands.

I bought this for my wife, and it's helped her so much that I bought one for myself. The companion app really helps keep track of the calories you take in, while the Fitbit keeps track of the calories you burn. It's a great device.

Gift for my wife. Good for burnt calories tracking. Nice to wear, battery lasts almost 5 days.

Great calorie counter and step monitor, it also keeps track of your sleep paterns. Very nice.

Awesome product at version 1. The features included in the app are just enough to get you started. Battery life on the unit is pretty good and lasts for days. When you purchase the Aria weight scale (sold separately) its a match made in heaven. Just step on the scale/step off and the Bluetooth sync will take care of the rest. I like the sleep tracker feature as well as I can now monitor my sleep patterns. I'm hoping that the next version of the Fitbit Flex will incorporate heart monitoring and blood pressure feature. Fitbit ...are you listening?

I love this tracker and the app. I don't do a lot in the way of exercise, mostly do to a hectic work schedule. However, I'm the type of person who seems to better when I have a record of things. I used to try to log walking and exercise but would forget sometimes. This tracker makes it so much easier. As a bonus it syncs directly to the app on my phone! I also use the Aria scale and the food tracker in the app.

Steps difficult to match to miles walked. If willing to play with or accept that, well, it's good. Sleep is very accurate.

Pro: affordable, can change colors to match outfits, provides sleep, steps, higher levels of movement (logs as exercise) monitoring. Allows you to log water and food. Cons: Does not tell time, alert for text messages or phone calls. Sleep monitoring could be more accurate. The normal setting for sleep is not sensitive enough and the sensitive setting is too sensitive for accurate sleep monitoring.

Great motivational and tracking tool to get moving and get healthy. My husband also has one and we have a friendly competition going to see who gets more steps each day. The calories in vs. out tracking on my iPhone and the web has already helped me to lose several pounds and gain stamina and energy. It really is an effective tool as long as your willing to put in the effort to get more steps, get moving and eat healthier.

I enjoy my fitbit. The negative is that I have had two defective units over the years but the good news is excellent customer service--they have always replaced it.

Love seeing how i slept. It keeps me walking. I like seeing my steps increase

it doesn't pick up all movement such as today I did 7 miles on the bike and it registered I did 2.66 the entire day. works well if running or jogging but bike or stair master not so good. Not sure the sleep data is very accurate as well since it will show I was awake when I wasn't. Some interesting data, good battery life and easy to use.
