I’m using this band for nearly 8 months.mi band has pedometer, sleep tracker in which it will track your daily sleep.and it will vibrate for incomming calls, messeges.alarm can b set in mi band.
Overall the product is superb and very useful.and once you charge the battery will last for 30 days.and for notification also the light will blink in mi band.
Its is good product for sports persons aur even fitness freaks for calculating their caleris burn.
