There's only a few problems with MI Band 2, of course, we can ignore those completely!

For example, Heart beat check - was a big flaw in MI band2, no body knows its accuracy levels!||



But the Sleep data is accurate! :)

With latest updates, they improved steps account accuracy too! I'm using this from last 2 months!

Other small features like Alarms, idle alerts are working perfectly fine!
