Piece of junk
I used this machine for six weeks, took it to my Doctors office today & they confirmed that it reads high.  I only had 30 days to return it, but it took me 6 weeks to get in to see my Doctor & get the machine checked. I thought I had dangerously high blood pressure, however, it was this machine that is defective.  Wish I could get my money returned.
