I am regular user of this product of xaiomi. this is really nice divice in 1000 ruppes and the thing many of people dnt know what it exactly does.
this track you daily activity like sleeping time, walking, running, every thing .
some times even you dont know that it also help to unlock the phone by connecting to it Bluetooth. I love that feature and it also help me to when I put my phone every where and it start vibrating when any call on my phone.
some time when I set a alarm for morning but I was difficult to awake with tune but vibration help me to wake up.
and seriously it get repeated until I get up from the bed . it force me to do that.
battery life is really nice it work for an whole month.
but its has problem that its strap is not quality my more then 2 straps are in condition that they are not usable any more.
and else things are good in under 1000 range.
