Query: readings unreliable....

bought this model to replace one of the self inflating ones purchased 2 weeks before this one.(not from amazon) Sent that one back because of overly high andunreliable readings. Based on select reviews about this one, thought this mighthave been a better choice. I have really high BP, so accurate readings beforechanging meds are extremely important to me. After a few days trial with this onei'm sorry to say the same problem exists. i.e. error readings, and extreme fluctuation of readings. Systolic to high, diastolic to low. Have older modelOmron, that use to be pretty accurate, but due to it's age(approx. 10yrs.) thoughtit should be replaced. But that one is still more accurate than the 432C. Whenyou have HIGH BP, you cannot afford to not feel confident of your readings.
