Personally I think all fitness bands ( available in market of all brands) are nothing but useless scrap and I have reasons for saying this . if you ever use one of them you know what I am saying e.g. You walk for accurate 2 miles but its showing all results except the accurate one like 2.5 , 3 or 200 but not 2 , like they dont have faith in human measurings they have their own measurement .Same sh* t happens with pedometer , take more the thousand step and you get to know the truth shows all results except the right one.
I never prefere a fitness band their are useless
