Did Not Work
I had to return this item. (And I have to take this opportunity to mentione that Amazon's return/refund practice is just exemplary.) It powered on OK. After that the Set (actually Set Up) function did not work at all. I was able to take blood pressure but it returned really confusing results after 3 attempts. (Display readouts show 30+% differences.) I don't think it's acceptable. (For ex: 170/100 is way too high but 120/70 is normal.) Otherwise, this item could be really easy to use and a good one in everyday life.
