This Fitbit Flex does not work and the charging cord doesn't work. Since we bought it for Easter a month ago, I am outside my return period. It was delivered timely and is cute, but doesnt function and since it was a gift bought for her Easter basket a month ago, we are outside the return period.

Stopped working the 2nd time I plugged my fitbit in. Definitely would not buy again.

It works okay and the longer cord is nice. However, after using the cord once, the battery ran down and won't come on or charge. I didn't realize to fix this,  I would need a charger with a reset button. This one doesnt have one. Not 5he company's fault I didn't know, but now I have a dead fitbit until I buy another charger.

The site serving the Fitbit Aria and you cannot complete set up. This has gone on for the past few days and nobody is able to fix it. The customer support is not helping either. You can check out the community.fitbit.com and see a red banner and no other helpful info. Worst purchase to date!

I haven't been able to use the charger yet because I needed to reset my Fitbit. There's no force reset hole on the back. I'd advise the creator to make sure this hole is included in the future, or you should just buy a replacement charger on Fitbit's website. It's not worth it to not have that hole just in case!

This product is defective.  Fitbit should order a recall or a credit.  I got an ERR message on my scale so I went on their site to see what other people had done to fix it.  I was stunned to see the number of people with the same issue.  The scale cannot be fixed and mine is out of warranty.  I have been a loyal customer with 4 trackers but Fitbit's response was to push a premium service on me.

It gets two stars because it's serving it's purpose even though I'm not happy. It's so hard to get the Fitbit In and out of. I'm waiting for it to break when I try to wrestle the Fitbit out of it to charge it. But so far it's not. I didn't read the reviews before I bought them or I would not of bought them. Also the clasp is terrible. It's also hard to get it to go into the slots.

Purchased this last year and the charging has been spotty.  About 4 months ago my fitbit stopped charging on this. I had gotten a new fitbit, but found it wasn't the fitbit but the charger that was the issue.  Don't see a customer service email or # to contact.

DOES NOT WORK WITH THE FITBIT CHARGE.  NO RETURNS! DON'T BUY!  It specifically says will work with the Fitbit Charge but it does not.

This product is advertized to work with the Fitbit Charge HR.  I ordered the first one and the Dongle did not look like the Fitbit Dongle and did not work.  I ordered a replacment and send an E-mail to the supplier that the dongle did not look like the Fitbit Dongle.  I received no responce.  I received a replacement and the 2nd Dongle did not work either.  I decided to order the Dongle from Fitbit.

I love my Fitbit surge, but sadly Fitbit doesn't make replacement bands. The wrist band is poorly constructed and not strong. Get another Fitbit that has replacement bands.

I bought this product about a month ago for my Fitbit Alta. After my third time using the charger, I found the Fitbit to be very hot to touch and the screen would not display. I let the Fitbit cool off, but it was still unresponsive.  Once a perfectly working Fitbit, now unusable.

They did not fit my Fitbit One. Unable to charge.

I guess you get what you pay for. The actual fitbit hr charging cable is $20, these weresults 2 for $6. Don't get me wrong, these cables do work, they charge, I've had no issues. The problem with these is that they do not properly fit into the fit bit. It takes me a good 5 minutes if wiggling and pressing to get it to plug into the back of the fitbit, where the actual fitbit charger snaps right in. It's like as if the mold of the shape  of the plug is off centered a little bit.

I don't know if I got just a randomly bad cable - but it is so difficult to get seated properly to charge my Fitbit.  I have a wiggle it around so much and then when it starts charging - I can't move it or it will stop charging.  Very frustrating!

While it does charge the Fitbit, it is temperamental.  Sometimes it works, sometimes not.  You have to make sure the connection is still good after setting it down. Connection is easily lost.  Its ok - for the price.

I have had the fitbit flex for less than 3 months and it will no longer hold a rcharge!!!  It's passed the return date and now, I'm wondering what to do.  Yikes!!
