The xaomi mi band is preety simle and elegant to use not like any other bulky device. It comes preety handy when it is about the battery life I have used the xaomi mi band for atleast 6 months and it is very useful and the battery life is just incredible it last upto 35 days as they say and it is fully water resistant so you don’t have to worry about getting your band wet and so on I used to take shower with the xaomi mi band on. At last but not the least it’s a great device and I have a preety good experience with it and it is as accurate as a calculator so buy it and have a great experience with it!
