Negative Positive
Title: (Consistenty) Innacuarate Reading
Review: The unit received to monitor my present high blood pressure condition appeared to provide accurate information and I was happy to see that my blood pressure was almost normal BUT unfortunately when my wife and I compared it with the doctors' readings after recent office visit, these were low and by definition useless. Thinking that it may only be a matter of calibrating it, I checked the manual and Ormond's webpage for this possibility but there was no information whatsoever. The only explanation in the possible differences between the HEM-790IT reading and what the doctor's equipment may provide was based on the fact that this equipment uses blood flow vibration, while the physician would have to listen and note for the systolic and diastolic blood flow characteristics AND that this unit "would compensate" for this variation. No matter if we used the "true value" (3 readings average) process, it still provided a low and unrealistic information.
Is the review positive or negative?
