Bests & Worsts Reviews from Amazon

This unit tested 22 - 36 points off on systolic and 12 - 14 points diastolic. Each test would measure higher and higher. On the last test, it measured 177/96. This freaked me out so bad I made an appointment with my doctor, took my unit in with me so she could look at it. She took my BP with her cuff and so did her nurse and then she took my BP with this unit. Both my doctor and her nurse got 138/76 and 136/74 which has been my normal for a few years now. I was advised to return this unit and purchase another one with a larger cuff which can also cause faulty readings. I returned mine after 4 days and 10 tests.
