Get any good brand Get your machine optimized and check the battery Monitor blood pressure once you are full relaxed both physically and mentally Dr Ashish Srivastava General Physician and Clinical Cardiologist

Hello there.  I can understand your concern.  The most accurate way to check blood pressure is by using a mercurial BP machine. But you wont be able to measure using that. So naturally other type of device is to be used. Omron makes good automatic BP monitors. But you have to regularly get your BP checked by a physician too. Best regards. Dr. Anil kumar jain. Bangalore.
