Regarding delivery,
There was a shipping error.
It had to be resent and the delivery took longer.
The product 'JA03' was good.
Overall evaluation is good.
The radiation intensity was displayed on the smart watch.
It is best to measure 'radiation' at intervals on the time axis.
However, the 'H.Band' app did not support three function displays: 'Radiation', 'Pressure' and 'MET'.
It would be good if the above three functions would be supported in a future update of the 'H.Band' app.
