For years I had a wrist unit and always good blood pressure, until you have brought me into the treatment of ergometer, because the blood pressure was too high viiiiel. Since the subsequent investigations showed all high blood pressure, but my wrist unit 100/70 indicated, I have thrown it against the wall and I bought this device. Lo and behold, the blood pressure is just as beautiful ... as in the doctor's office. The measurements correspond roughly. That you can not turn off the voice that I find not bad. A little quieter place, but would be fine. But twice a day I hold the degree of even so.
