iFixit tears down the Fitbit Flex:
Here at iFixit, we promote only the healthiest of lifestyles. We eat our vegetables at least once per week, and we never eat pizza two days in a row (unless it’s leftovers, of course). One might go so far as to call us health freaks. We would not argue.
But we are iFixit, so of course we’re sacrificing our fitness ambitions for science. We ripped into Fitbit’s newest pedometer/heart rate monitor/sleep tracker wristband. What kind of a diet helped this thing fit into its tiny jacket? We’re about to find out.
