Well made and documented. But not accurate enough for me, so I donated to Goodwill.
Am nut on BP monitors and have gone through many over past few years. Went to A&D brand based on experience with several models that were always close to what got the traditional way at doc's office.
Wanted wrist model to use at gym, but gave up when readings varied from close to same, to 20
percent higher than my current A&D upper arm model, with no apparent reason for the variation. Pulse rate was always close to upper arm model reading, however.
Placement of cuff relative to wrist was touchy, to say the least, and had a major effect on reading got,but again, I could not see a consistency of reading versus cuff placement.
I recommend the upper arm models. I have had several A&D models and all worked fine and were close to my doctor's mercury tube model's readings. I choose based upon features I want.Get more detail about LifeSource UB-521 Digital Wrist Blood Pressure Monitor.
