Anonymous7 years ago000Is it normal that the unit makes a rather irregular motor noise when building up pressure at the cuff?Show in original language (German)dhoffman7 years ago • purchased this product000purchased this productMy machine is a little louder for about 2 seconds at the beginning of the pressure build-up and then becomes quieter and stays that way during the entire pressure build-up.
