Not accurate!
The Omron HEM-773 was recommended to me by a co-worker who was very pleased with the instrument. Since we both work in a hospital and have a good working knowledge in the area, I thought that this would be a slam dunk purchase.I could not have been more wrong.The reading varies from 10 to 15 units off from manual readings from 3 different well trained nurses. The unit is very easy to use and good features for the money but if I don't have confidence in the reading, what good is it. I rarely get it out and when I do, it just makes my literal "blood pressure" go up by it's misreading.I would think that a instrument such as this would have a calibratiion mechanism.In all fairness my co-worker loves hers but I bought mine here and am not happy.
