We use our own at home, cuff based automatic machine. Wife just bought me a newer one, the older one must be over a decade old with CVS lifetime warranty, new one is Omron 10 Series BP7450, like it a lot, good score from consumer reports too. Accuracy got a 5/5
Of course I still take notice of the readings my Dr gets.
They have always matched up with the Drs office when done manually by them. Dentists and other practitioners, its almost criminal how out of whack these devices are, more so the wrist machines. They shouldn't even bother.
Some might think I am a bit of a health nut at my age and for the last couple decades but the reason is I am determined to avoid the death sentence of heart disease that had prevailed on one side of the family for generations, So far its working my typical BP is 110/65 and honestly sometimes much lower, other times it can be a little higher.
