Negative Positive
Title: Easy to use but disappointing results
Review: Based on the reviews I purchased 2 of these, one for my mother-in-law and one for me. I found them very easy to set up and use. However, my mother-in-law's systolic pressure would run 10-15 points low on this monitor as checked against her doctor's results, and at age 88 this is her most important reading. Both of my numbers would vary by 10-15 points in either direction compared to an arm unit that had been calibrated at a doctor's office. I liked the units and found them easy to use but the readings were so erratic as to be unusable, so I have returned both.
Is the review positive or negative?
