I bought mi band 1 s 8 months before but I am not happy with it , it does not have a good sensor and does not give aacurate data but main problem is it mostly get disconnected .
It is connected to mobile by mi fit app through bluetooth but it does not get connect and have a problem of connection . It loses it connectivity even when we are using it and create a problem for us .
The connectivity problem is soo high that I had to stop using it and all my money got wasted .
