Getting consistently high readings compared to doctor's office. At the doctor they had two nurses and the doctor take multiple readings. They were getting 135 over 85 while the Withings unit was getting 178 over 115 and then got a 220 over 125 reading (meaning I should have had a heart attack for hypertensive crisis). Since I'm still alive my conclusion is that the unit is defective. I really liked the WIFI upload and easy to use cuff. Returning unit for a refund.
