Mi band I used personally frankly speaking great band to use. The day I open box I found a band, a piece of device and small little charging cable for device. I wandered first what this little device can do. It can count your steps, burnt calories, remind of you calls and messages. Battery back up it can last more than 30 days??????.
It God hidden feature which many of you di not know; you can wear band ten set alarm in your mobile, band will vibrate in morning and wake up you without disturbing another person. Display is not present in it but I want to say something to you, no display great battery back up. so grab this device.It is water proof also.
