MAny co. Are there in this price range but all other lacks in accuracy. Mi band is highly accurate tracking device
I m using mi band for past 7 month and im pretty much satisfy it help me alot in achieving my personal goals.
Mi band features amazing 30-40 days battery backup for me amazing thing is that it can track my sleep cycle it will tell you at what time you slept and at what time you woke up and it also tell you about how many hours you had a deep sleep. Miband also notify you when a incoming call come by vibrating the band.
