Bought an Omron blood pressure monitor in Adelaide a few years back, over $100, shortly after we visited the US, found a better featured Omron for $30.
I have an Omron too, as does my Cardiologist when at his Suburban surgery.
He gets me to use his device on my annual visits .. checking my technique I suppose. I take mine along to check calibration against his. It's always correct.
BTW, he is only interested in the first reading, (Systolic) and has me take 3 readings in succession as I do at least once a week. He puts a big cross through the Dia & pulse recordings if I was dumb enough to record them & gives me a lecture on why the Dia is of no importance. My GP prefers them all.
Other half is in hospital 3 days a week. I've taken our Omron in & compared it to the Welch Allyn Connex Vital Signs Monitor. Doing alternate reading a dozen times in a row. The Omron was the same within reason, maybe a touch higher.
Also used the hospital's Welch Allyn 767 analogue pressure gauge. It works just as well.
The nurses are more than happy for me to take readings to save them some time.
