Its been 7 months I am using Mi Band 2 . I Wear it most of the time. Its better than Mi band 1, The display in band is very catchy . It has like 4 to 5 functions of displaying of STEPS, TIME, PULSE RATE, DISTANCE. It is connected to the mobile
(android or ios) via Bluetooth, and there is Mi fit application available in the web store through which the band is connected
and we can track the daily activities.
We have an option for call and message alerts -say while we are in motion either running or riding.
Earlier there only phone symbol would be displayed on band on alert and it would vibrate, but the recent update on firmware released by Mi, where the name or number is displayed on band -cool update.
Best feature of the band is its battery, once charged it will last 20-30 days .
It is very used friendly as there is only one scroll button on the band .And the band can be replacable if damaged, variety of colors are available.
Cons-
While connecting to the second device there was error, and then re-connection to the 1 st device was not possible through Mi fit app(pairing problem).I tried to contact the Mi customer care, but the response was very poor.
I had to connect my band through third party software { Notify and Fitness for Mi Band 2}
Now it is not displaying heart beat.
According to me, if you are going for a band which is affordable and which you want to connect to single device
This is the ONE
