Hii guyzzz,
l recently parchased my mi band 3.great built quality, and amazing battery life.l haven’t had to charged it yet and have own it for two weeks.This band have decent adjust-ability and is comfortable.The electronic piece can be a bit difficult to snap into the band, so those with arthritis many want to look at other options.The only shortcoming of this band for is the lack of a barometer for determining flights of sairs climbing/altitude chage.
