15-25 points low

Have measured this against a mercury which is the one used for calibration. The Ozeri is 15-25 points off on the low side. I certainly wouldn't recommend this product if you're measuring your BP for hypertension. Unfortunately, it was easy to use and easy to transport on travels. But even if you add 15 to the Ozeri measurements you may be 10 points low, but there's no other way to tell unless you measure your BP with a reliable monitor, so what's the point of using it.
