The Fitbit Flex is simple way how to track steps, sleep and calories, I prefer light design and its really comfortable to wear! Fitbit Flex works on bluetooth what its really usefull! For exemple I am playing basketball and I am using it every day!
Fitbit Flex is taken to monitor sleep, wake up in the morning VAS Tise you can check how long you slept many times you awaken during the night.
VAM burrow through the Fitbit Flex calculates calories burned, number of steps distance you traveled Take time spent on different activities.
Flex has a pleasant, waterproof bracelet in different colors. For many will be so stylish fashion accessory.
