I have been using Mi Band 3 for almost a year now, and I must say that it has been quite an ease for me, as I travel or I am busy at office, and dont have enough time to go and check my phone for all the notifications I receive, I can just easily look at my Mi Band 3, and if I see a valuable notification, I can pick up my phone, and same goes with the phone call. I dont have to see my phone to know whos calling, everything is visible from the Mi Band 3, and if I dont want to pick up the call, I can easily disconnect. I can track my activity, how many steps I walked, or much hours of sleep I got. The good thing about Mi Band 3 is that its cheaper, and of a supreme quality, with Mi brand on it, which makes it more authentic and reliable, and with the number of features it offers, its quite cheaper than other variants with the same number of features. I really have to say a word about the battery life, I went on a vacation once, and forgot my Mi Band 3 charger at home, well, I didnt have to charge it until I got back to my place on the 7th Day.
