Customer Ratings & Reviews

I have always had the FitBit One and loved it. When I saw that the Flex 2 did everything the One did AND I could wear it in the pool is a BIG bonus. I haven't tried it out with the weather being cooler, but can't wait to try it there. I wouldn't expect anything less than the best from Fitbit though!

Flex 2 is perfect. The band is already cracking after only a few months. Not used while swimming.

I like this bracelet tracker but it's a pain to charge. It sometimes wont charge overnight. Possibly the pins are not lined up, but this is hard to see and makes it difficult. I have not used it as much as I did my previous fitbit item. I'm just lukewarm on this. b/c of charging.

I wanted something economical for tracking running and swimming, most the trackers in this range doesn't support swimming including Fitbit charge2 but it does, quite good in what it does, only problem is charging. Recommended to others who are looking for good options in this price range.

I love my fitbit! I use every day! Tracks nicely but sleep tracking seems to be off calculations.

I've had a number of Fitbits everything from the One to the Blaze. After my son gave me an Apple Watch for my birthday I decided to go to a more simplistic Fitbit. I love that I can still be apart of the Fitbit challenges with my friends and still get move reminders and track my sleep.

I've owned the original Flex and decided to buy the Flex 2. Though it seems better made than the first generation, I still don't expect it to last more than a year. Overall, it's a nice simple tracker that lets me use the Fitbit platform, which is better than what I have on my Apple Watch.

Good product. Simple fit bit for exactly what I want without all the extra bells and whistles.

My Flex 2 has proven to be a great motivator and an important addition to my fitness regimen.

I bought this to replace the Original Fitbit Flex (which was awesome) and I'm impressed with the updated version as well, because it's water proof, so you can swim with it. However the sleep tracking, is not as accurate as it should be, but other than that I'm quite pleased with it.

I purchased this as a first fitness tracker. It's light and easy to wear, battery charging is fast, and the mobile app is perfect for tracking your steps and activity via Bluetooth. The mobile app allows you to enter weight, sleep time, hydration amounts, etc.. and more.

My fitbit is the perfect motivator. It's easy to use, and the charge lasts a long time.I can wear it in the shower and in the swimming pool! Syncs perfectly with my iPhone and gives me all the data I was looking for. Great motivator to keep on the move ! And I love the purple color !

This little fitness tracker dose the job just fine. If you are looking for something simple that motivates you to get up this is the one. The updated ability to recognize when you start exercising is great. Only complaint is battery life. It last lasts about two or three days.

Having used the original Fitbit Flex for over two years, this is a great improvement. The design is no so bulky, so it is much more comfortable to wear, and the new clasp system does not come undone like the old ones did. I also use this for swimming, and have found it to be great so far.

I like my Fitbit flex a lot. However sometimes it doesn’t seem to record my sleep accurately

Great value for price. I got this as a gift for someone in my family. Perhaps not the most stylish tracker on the market, but definitely does the job of getting you motivated. I have bought cheaper trackers in the past, but the reliability of this one justifies the price difference.

Love this little thin weightless tracker. Only 1 sml problem for me or someone with low grip strength. Worked it out by using needle nose pliers to close clasp and re-open it to remove it. It IS waterproof / splash proof. It does what it's intended to do. PERIOD.

There isn’t anything I don’t like about this device. It’s simple but the app is the best.

With so many varieties out there, we were not sure which Fitbit to purchase. This is a very simply, easy to use option. Set up was simple and the app makes this very motivating.

My daughter is taking an online personal fitness class and needed a tracker so we got her this Flex 2. It is small and does what she needs. There are also multiple band options to purchase separately. The bands that go on like a watch are much easier than the one that comes with it.
