Cons
Con Very unreliable build quality
There are many reports of the track malfunctioning right out of the box or after only a few hours of use. This includes the LED display not working, the heart rate function not working, and buyers being sent used products.
Con Heart rate monitor is very unreliable
Along with frequently not working at all, it has a tendency to be quite inaccurate. It struggles to read the HR when you're sweating as well so isn't useful during exercise.
Con Underwhelming battery life
The fitness tracker's battery lasts about 3-4 days on average.
Con Can't be paired with external HR monitors
The Fitbit Flex 2 fitness tracker has no built in heart rate monitor and lacks the ability to pair with external HR monitors.
