Bests & Worsts Reviews from Amazon

I have tried this blood pressure monitor on 3 different people. It is showing very high readings especially on the one person who does not have high blood pressure. Went to my local store and got a true reading from theirs which is much lower. Would not recommend. And I can't return it because I thought it was fine and the box went out with my recycling. Already ordered an upper arm cuff. Will not use a wrist cuff again.
