Summary: Been 2 years now since we got this. Still works . The only issue is you have to follow the instructions. you have to sit upright and hold the hand close to your chest. only then will you get correct readings.
Summary: I purchased this a few months ago and it works fine. Better than the old style machines. However, it quit working after a few months. It was also hard to hear the beeping it was supposed to have while checking it. I wouldn't recommend it for the price.
Summary: After by-pass surgery my husband had to monitor his blood pressure daily. Because of restricted arm usage, the way this monitor reads your blood pressure made this task so much easier and convenient for him to perform himself. I would highly recommend it to anyone.
Summary: I first ordered the Omron 650 from Amazon in January. It arrived but would not inflate. I returned it to Amazon and received a prompt replacement. The replacement inflated properly but under read by at least 20% as compared to a accurate upper arm reading at my docters office.
Don't listen to the reviewer who got a defective unit...

Summary: I use this unit daily to monitor blood pressure, and I have compared the results to multiple Doctor's (old-fashioned) readings as well as machines in pharmacies and medical offices. It is accurate. Usually it is spot on, within 2-3, and any differences were not statistically significant.
Summary: Just received and tested it against another blood pressure monitor that is accurate. Average systolic for this model is 22 points low and dystolic 14 points low. Checked three times against the other monitor and consistently off by 20+ systolic and 12+ dystolic.
