Comment:
I got the Fitbit Flex as a Christmas gift from my wife. Once I set it up, it was easy to work with, comfortable and lightweight and synced easily with my iPhone and Android phone. However, about eight months later, the bit died. The company doesn't want phone calls (no phone number anywhere on its site) and sends a we will get back to you message upon emailing support. Unfortunately, the company either does not respond, or responds up to a week later. I am still waiting for a reply from an inquiry sent almost a week ago. You will not receive much support if you have issues and I am exploring other brands. <br />In addition, my wife and I walk together (I bought her a Flex for her birthday 6 months ago) and our trackers differ SIGNIFICANTLY with the results. Same pace, same distance but hers will show half the active minutes as mine and less mileage. When support DOES reply, they send a standard script that men and women are different, results differ by gender, etc. Kind of suspicious that we walk the same distance, but hers records LESS. So between the inaccuracy and the lack of support, I would not recommend this product as a long-term useable fitness product.

Fitbit flex seemed to be working fine for about 2 months. Then one day it no longer worked. Even though it showed it was fully charged while in the the charger, when placed back in the wrist band it failed to show any lights. Contacted tech support and was told my unit had to be charged again. I jumped through all the hoops they told me to and still no luck. I was told to contact the place I bought it for a replacement. Lucky for me they took it back.
How long have you owned it:
One-to-three months

No, I would not recommend this to a friend.
