Hi guys, I purchased this band 15 days ago in amazon.
It is one of the best band at this price. It is weightless and you can enjoy.
If you connect this with phone using bluetooth, the charge lasts upto 23 days.
If it is not connected with bluetooth, the charge lasts upto 1 month.
It is very easy to use and the mi app gives accurate data.
It has sleeping monitor, walking distance and steps calculated.
I dipped this watch in water for 1 hour, there is no problem with this. Water proof is good.
Worth buy this item
