I have used the mi band for over one month. There are things to love, there are things to hate.
Good Things
The band works with any android phone. The software is intuitive, the device is hassle free and the battery lasts for a month, so you wont have to worry about constantly charging it. Its does remarkable job of differentiating between a long walk and walk on treadmill.
Bad things
It doest have smart watch. More importantly the mi band isnt a classy accesory.youre not going to go to a wedding or a formal party with this on ur hand, next to your Tag Heuer.its waterproof but its comes loose when you doing laps in the pool. In summer heat it chafes the skin.Some people dont mind having it on the hand while sleeping, but even aftet a month. I just cant get used to it, which makes the shake-to-alarm feature worthless for me. The Mi bamd does a great job of tracking fitness but it is not a motivator nor does it provide information needed by anyone who is health conscious.
