First-sale date unconfirmed	Oscillometric wrist measurement; HEM-6161-E. First on-sale date not established; older HEM-6121-E RS2 is different hardware
Accuracy
Accuracy	Exact manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse. Systolic range 60–260 mmHg, diastolic 40–199 mmHg and pulse 40–180 beats/minute; cuff-pressure range 0–300 mmHg is separate	Maker's pressure accuracy ±3 mmHg and pulse accuracy ±5%; systolic range 60–260 mmHg, diastolic 40–215 mmHg and pulse 40–180 beats/minute
Clinical validation
Clinical validation	Manual gives an unspecified clinical-test maximum permissible standard deviation of 8 mmHg for systolic and diastolic pressure, without identifying a published study. Medaval reports no peer-reviewed clinical validation information for BC 28; headline independently established validation omitted	Medaval attributes STRIDE BP adult self-measurement recommendation to HEM-6181 equivalence, noting that the unpublished assessment cannot be verified against MDR requirements. Exact manual says pregnancy use has not been validated
