I have the OMRON M6 comford blood pressure monitor for over 10 years, and that's why I also bought a second blood pressure monitor, the M3. I measured with both and they had a deviation of 0.2. Unfortunately, this one has memory for only one person. It is manufactured in Vietnam. It comes with a three-year warranty from the store and there is no manual in Greek. I was probably lucky because I bought it yesterday for 50 euros and today I see it for 66. The only negative thing about it is the fake leather case. It's slightly better than a paper bag! That's why it gets one less star! For 50 euros, it's value for money, for 66, I don't know!
