The product itself is solid, the issue is more with taking BP at the wrist
on December 31, 2013
From Sheldon G. Sheps, M.D. via the Mayo Clinic website as retrieved 12/31/13, in response to; "How accurate are wrist blood pressure monitors?"
"Wrist blood pressure monitors are extremely sensitive to body position. To get an accurate reading when taking your blood pressure with a wrist monitor, your arm and wrist must be at heart level. Even then, blood pressure measurements taken at the wrist are usually higher and less accurate than those taken at your arm. That's because the wrist arteries are narrower and not as deep under your skin as those of the forearm."
The BP7, not by nature of a flaw in its design, suffers from the above. Most people are going to experience higher results on a wrist monitor than they are one that goes around the upper arm. So if we understand that, and set it aside in favor of the increased convenience of a monitor for the wrist, then what we're left with is an attractive and well designed instrument that also offers an intuitive iOS application that allows you to track history.
The rub, of course, being that you can hardly view the results as anything more than high-representative of where your BP may be, but then few seek medical-grade precision with home instruments. What this can do, and does well, is provide consistent results. Which is to say that once you have an idea of how high it runs for you (and heed well Dr. Sheps's *and* the manufacturer's clear notes about the all important angle -- the app won't even start until it's right enough), then you can make reasonable assumptions going forward about what variations to those readings mean in terms of your current levels. A high baseline can still be informative insofar as maintaining the same, or coming in perceptibly higher or lower than normal, gives you a general idea of where you stand.
I think it would be easy to rate this product lower based on high results, but after doing some digging and trying another form of wrist reading, my own experience has been that iHealth has produced a quality and affordable wireless monitor here; hence the rating. Would have liked an on-device display and control option, even a small one, for times you don't have or don't want to use the phone, but that's a pretty minor note as it would likely mean a more expensive device. Pleased, noting the caveats as above.
