Italian Review & Video



FitBit Flex was one of the best FitnessTracker. It has 5 LED, each light represents 20% of your goal. Choose what to detect: steps, calories and distance. Thanks to the accelerometer forefront of Fitbit, Flex calculates the parameters, such as calories burned, according to your personal profile, reflecting in detail their stats.

For night mode, FitBit Flex, monitors you how many times you woke up, how many hours did you sleep etc …
You can set the alarm, which is quiet and wake up with a mild and gentle vibrations.

This device is now dated, competition beats him at both the price level and the actual level of functionality. It was a very good product to launch, when I’ve bought it, but now it is one among many.
