It is a smart band looking very smart in hand. I bought it few years ago and used by me only. It has amoled display, calling, notification, exercise tracking, running, specially it is a 100% waterproofed and you can always wear even odu, bath etc. Super connection by mobile. Heart rate monitoring, SPO2, steps counter, calories counter etc. Just one issue Battery backup is low. You may change the battery easily. All others 100% okay.
