Difficult to say

I have long time all sorts of reviews on sphygmomanometers read here at Amazon and also all my reviews Stiftung Warentest read pinibelst. Then I have this M500 for the upper arm and give the RX Classic II ordered (2.3 tested by SWT).

Now I do not know if it is because of my veins in the wrist, but the instrument for the wrist has much lower diastolic values ​​appear as this M500. By comparing device measured, it was revealed that the M500 measures properly and therefore the lesser went back (RX Classic II). However, it confuses me that it has as good test results in testing, but also in the pharmacy told me that some measuring devices for the wrist are not just suitable for all people. If you have high blood pressure problems, which should be monitored at home, then I urge you to test both types of devices (for example at the doctor or at the pharmacy). I also have two devices tested at several test persons in the family and in all the RX had lower readings. For me, these differences were indeed most clearly, but still, after all, a difference has always been to identify, in each measurement. I wonder if it is on the unit or the physical constitution. I am also quite sure that we have done everything right, because I am so very well acquainted (at heart level, not speaking, not moving, not tense muscles in the arm as possible, 5-10 minutes to rest before ...). Therefore, we have opted for the M500 and are absolutely delighted.

Toll I found, however, that measures during inflation and the measurement is very fast.
