Disappointing!
This was a very disappointing purchase, but I was able to return it easily and at no charge.  For my wife and for me, it registered alarmingly high.  We used it properly and have been using wrist blood pressure monitors for many years.  We also see our physician regularly and know what is are normal ranges for us.  Accurate blood pressure readings are important!  Otherwise, why bother?  After trying this unit for several days and comparing it with other monitors, we finally gave up and returned it.
