I got a Fitbit Flex yesterday. First of all, I amazed the amount of its information is so small.
How to set it up? How to charge the battery? In the begin with, I did not know what is the power source for this gear. Fortunately, there are much information on the some web site and FAQs.
The device may useful to manage the indicators for my health by monitoring and control them if I can control my stomach.
