This automatic Omron bp machine gives results all over the place. Left us w/ a bad taste in our mouths. She's getting resigned to just taking them herself or buy a more expensive bp machine that at least is pretty accurate.
We've had good luck with the Omron's when they're used correctly, and they're easy to use wrong (hand HAS to be on the shoulder or on the table at heart level, etc). Still, hit e-bay - we have FOUR of the Criticon monitors we bought, and the most we paid for a strait BP was $50. The weird one I have with a pulse-ox built in was like $100.
