Query: Convenient

The Omron HEM-670 is convenient to use, store, carry, transmit readings to computer, edit.However, I plan on comparing it to the doctor's blood pressure equipment's reading at my next check up. My Omron HEM-670 always gives me a read out of lower than 120/80. Typically it reads approximately 113/73.I agree, some days I might have low blood pressure, like today I was EXHAUSTED so I checked my blood pressure in case low blood pressure was the culprit. Omron HEM-670 read: 96/58. Nothing to be afraid of. It would have to be 90/60 to be borderline low. I'm still healthy.I always wonder if my Omron HEM-670 is reading maybe even a tiny bit low. I wonder why I can't reach 120/80.
