Hi guys. I have been using a MI band for over a year now and a lot of bugs were faced by me in the run. The MI band stops charging somethimes and suddenly it starts which is a big concern.
The app also finally got a bit high end or else the old MI band app was a disguised app. Also the MI interface is active and the band is quite accurate.
More of its downsides is the charging capabilities and the interface.Or else at 999( now available for 700) for a basic activity tracker it's a good deal.
