Bests & Worsts Reviews from Amazon

I thought I was buying a top of the line replacement for my old Omron BP monitor which finally stopped working after 10 years. Right out of the box I noticed the new monitor was reading 12 to 20 points higher than my typical blood pressure for both diastolic and systolic. At first I thought my blood pressured suddenly increased until I checked it at an in-store BP monitor. I tried different cuff angles, sitting positions and the unit continued to read high. I finally took it with me to my doctor's appointment and both the nurse and doctor confirmed it was reading high. The error was also inconsistent. I called Omron's customer service and their basic attitude was that each monitor is checked before it's shipped and that I'm probably using it wrong. I confirmed that my arm size was well within the range of the universal cuff that comes with the unit. I also went thru the method and technique used to take the readings - cuff position, arm elevation, proper seated position - all per their user directions. They were more interested in defending their product than listening to all the ways I tried achieve an accurate reading as well as my doctors results. I've been monitoring my BP for over thirty years, starting with manual hand operated cuff pump units and a stethoscope. The call ended with the rep saying you can ship the unit to us, but we will more than likely find that it is calibrated correctly and you will receive the same unit back (at my shipping expense)! Beware, Omron's warranty does cover not shipping. After the call, I read more Amazon reviews and found others with similar problems with this model. I returned the unit to Amazon and will look for another maker.
