The mi band by xiaomi according to me is the best band till date at a price of Rs 1000 the best fitness band
It uses bluetooth to connect to your device and ya its rechargeable the battery last for 1 month but usually it gets over under one month I just totally love it The band tracks all your momments how many steps u walked how many calories u burn The look of the band is classy we get a charger with the band it does no have a display but it has 3 led notification light on top The band starts vibrating when u get a call , text to remind u
You will have to install a application on your phone named mi fit were you will get all your statistics it even records your sleep data how much do u sleep what kind of sleep deep sleep or light sleep and you can even set an alarm ya the band will vibrate and will wake u up
