I bought both a Sanitas Wrist Blood Pressure Monitor and an upper arm blood pressure monitor. After extensive testing I can recommend to anyone the upper arm blood pressure monitor. It is intuitive to use and leads to very accurate results. However, the wrist blood pressure monitor, I advise strongly, because the measurements are inaccurate. I can measure the device several times in succession and the results are greatly deviated from each other even though I had the power all the time on the same wrist and did not move me between measurements.
