Negative Positive
Title: Erratic...and unacceptable
Review: This product is totally unsatisfactory as a health monitoring aid. The results are erratic and not reproducible. It gives WIDELY different readings on left and right wrists (Yes, I changed the calibration as directed.). It does not agree even "in the ballpark" with an automatic arm cuff model OR a manual cuff/stethoscope. The much-vaunted APS system is a joke, inflating and registering only at crotch-level when on the right wrist!?! Steer clear of this product; mine was returned after a very frustrating afternoon of trying to get it to do ANYTHING in a repeatable fashion.
Is the review positive or negative?
