It’s really a great product. Nicely track all the activity. It can be easily synchronized with phone using Bluetooth.

Having used 4 different fitbits over the last 3 years this is one for me is the best of the lot. Sleek, waterproof, cheap and a long-lasting battery make it a perfect fitness wearable in tandem with the fitbit app. Would highly recommend

Not good.

I like this a lot. The only reason I have it 4 stars instead of 5 is because one of the two I purchased didn’t vibrate at all. I did everything I could think of to no avail. I had to call Fitbit support, but they were great and are sending a free replacement Pebble. I’m just bummed that it never worked from the start.

Upgraded to this from a Fitbit Charge. I loved the charge but after a year, the battery wouldn’t hold a charge and the band literally fell apart. This wasn’t the fault of the Fitbit; I work in a cafe so I’m constantly washing either dishes or my hands. Even being careful it got wet a lot, and I suppose even water resistance has its limits.
The difference between water resistant and water proof is why I went with the Flex 2, as opposed to just getting another charge So far it’s held up beautifully, I do try to remember to take it off at the end of my shifts and wipe it down, just to be sure.
As for actual functionality, I’d say it compares well to my charge. I like the minimalism of the display, and the clasp on this band is MUCH better than on the charge, which popped off my wrist more than once.
I especially like the various alerts, including the reminder to get up and move. It’s motivated me to take laps around my kitchen island to get my steps a couple times. No shame! And as someone who regularly gets up before 5am, the silent alarm is wonderful. It wakes me up easily without waking my husband. That’s a huge bonus in my book.
Overall, this seems to be fairly accurate in terms of step count, although I’m not as dogmatic about that as some people. I just want to know that I am moving throughout the day, and that I have some accountability to myself when it comes to reaching my goals. The only thing I wish is that I could set the auto-detect for active minutes a little lower. My walk to work takes about 7 minutes, and if I forget to turn on exercise tracking, it doesn’t always get counted. That’s honestly my only gripe and it’s a small one.
This is a great tracker, it works well, charges quickly, and once it’s on my wrist I forget it’s there. It’s been a great help in striving for my fitness goals.

so i got this band on 9th night i charged it fully and started using it from next day early morning, I have used it for 2 days so far and the battery is showing at 50%. One grouse is that the sleep tracking is not automatic I have to switch it on from the app after switching on bluetooth. this beats the whole point of things as by the time i get around to doing these things I’m no longer sleepy and it takes another 15 to 20 mins to sleep. Another missing feature is the food tracking, there is zero input for Indian food, maybe it should not be sold in India if this simple feature can not be incorporated. Maybe I missed something in the first 2 days and there is a way to counter both my problems, if so please someone from Fitbit please enlighten me else i will be returning this product in the next 2 days. So far no value for money compared to many cheaper fitness bands.

I have been extremely disappointed with the new flex. I had my old flex for two years, had to change it out once when the pebble died. However it was always extremely accurate, both in steps and sleep tracking.
I got the flex 2 about six weeks ago. Here are the issues I’m having.
1. It does not accurately count steps. I averaged about 1700 steps per mile on my daily walks. Same walk, same duration every time. The flex 2 averages about 1000 steps per mile. I just tested it in my house, I walked 150 steps, it registered 122. Ridiculous
2. I have always used the “track exercise” function instead of relying on the flex 2 to recognize when I’m exercising. This week, doing my same 3 mile loop, despite the mile times showing for each of my 3 miles, it records my walk as 2 1/2 miles. And 2800 steps total. ( 1,064 step miles have been recorded for men running a six minute mile. ) I am walking a 12:30 +/- mile. Again, ridiculous.
3. It says that I never wake up, and I am only restless two or three times a night. I have a baby monitor by my bed for my twin infants. Trust me, I wake up plenty. Even when they are sleeping, I am often restless and flipping around, as my husband will attest. When I have put it on sensitive for the sleep setting, it says that I am awake all night long, also not true. I had to sleep sitting on regular for the flax and felt like it was much more accurate.
I feel like overall the flex two is junk. And I LOVED my flex. I just wanted something reliable to count steps and keep me moving. It’s frustrating I can’t do the basic job it’s supposed to be designed for. I would return it and ask for a new flex 1 if my month wasn’t already up.
The two pictures show the exact same walk, two months apart. I am walking faster now, but I am back to the speed that I was walking a year ago. The step counts did not vary that much last year fast vs. slow with my original flex.

I recently acquired a used Fitbit Flex and have been trying to get in some more exercise. My teenage son was pretty impressed especially since there is an app for his phone. He talked me into buying him the Flex 2 and it arrived yesterday. The shape is a little longer and thinner but similar, however the bands will not interchange with each version. As far as I can tell, the Flex 2 does pretty much the same as the original Flex except that it is OK to take it into deper water such as a pool or swimming at a beach while the original is OK in the shower or washing hands. Setup was simple for both Fitbits, mine on an old iPhone 5C and his on an old Android. The app installed flawlessly on both phones. Once set up, both Flex’s seem to operate pretty much in exactly the same way, counting steps as your arm swings, estimating calories burned and monitoring sleep. He especially likes the cool alarm function. Our goal is to walk together but not for competition as he is in much better shape than I am. It was a very long time ago when I was a Marine!
The charger is a USB type and can be charged in any USB charging port either in a wall, a computer or ahub. The chargelasts for many days although they advise to recharge every few days to be sure it remains charged. Also, the battery life is displayed on the app.
This is a really neat little device that makes tracking your exercise interesting and fun. I’m sure in the future there will be a GPS/phone version but for now my son is happy with all this little pebble does.

A quick review of the fitness track I purchased during the Great India Sale (Sep 2017) after reading the seller review (Fitbit) what all features being offered and ease of the usage of the watch and backed by the app assistance.
What’s Nice about it is :-
1. super lite. You don’t realize that you are wearing
2. elegant & smart design. You can keep wearing it even during the formal get-togethers or outing.
3. the snap clip is stylish, simple & keeps your watch in the wrist
4. Two sizes of the band
5. I bought blue color which is looking simple & elegant
6. Battery back-up pretty nice. For now its holding on to atleast 4 days
7. Water proof
8. Take’s into account the sleep pattern – what time do u finally sleep, sleep duration, sound or disturbed sleep (in btn tossing & turning)
9. Vibrates on receiving call, sleep wake-up I didn’t feel it. My alarm on cellphone woke me up. It could be probably because of gentle vibration.
10. Coz of the design u can wear both every day watch & the tracker.
11. The app is simple, easy to comprehend & sync.
Whats not so nice :-
The data being generated i felt was kind of in-accurate –
1. while i was asleep it calculated the “steps” and calories burnt ! Did i get up do a sleep walk ? Showed 270 odd calories burned
2. One day i just sat around the house & didn’t do any physical work & it calculated and gave me a badge !. Showed erroneous calories burnt & steps done !
3. The price which is pretty steep for Rs 7000/- plus
The seller was Cloudtail & Amazon fulfilled service.
