THis machine l have always measures different numbers each time l measure my blood pressure. It always goes about 10 numbers off each time.

Bring it with you when you go to the doctor is and check it against their BP readings. Even at the doctor is you can get several different readings.

They are much better than they used to be years ago, they are not as accurate as manual BP that drs and other health professionals use but for the money they are fab! Especially for those who get worked up before going to get it checked, so it wo not be a true reading.
