Just is just the best band for the money you are paying for. I had mi band 1. And it lasted for a long time for me. Therefor I bought this one wishing the same. Battery would last you more than 2 weeks if you don't use heart rate monitor continuously. Screen is okay, not so bright. Touch works really well, no need to take off when you are in the shower. Sleep tracker is good to see how good or bad your sleep was. Only con is the charger, it's a special usb cable for the band.
