Hunter's comment
What is a smart band that tells me the current state of my body while exercising?
The product I introduce here is a very useful wristband which shows my condition.
It is smart product that automatically tracks blood pressure, heart rate, activity trace, calorie etc. and informs to me.
It's also amazing to be able to connect to my smartphone via Bluetooth to make call alerts, messages, alarms and even stopwatches.
