Having already purchased the EW-BU30 for me and my wife and we were very happy, I have recently purchased the new EW-BU15 for my father. The measurement results are very accurate and the new scale of the cuff, errors can be avoided when measuring. The cuff is thus always perfect. In particular, the award of the German Hypertension Society has prompted me to buy. I can the other opinions on the measurement accuracy not connect because the device is working properly. According to WHO (World Health Ass.) Should always at least between measurements. Pass 90 seconds to get an accurate result. The veins are recovering from the cuff pressure, it also has my doctor confirmed. I am very satisfied with the device and the operation is very easy even for my father.
I am particularly convinced again and again the blood pressure measurement during Aufpumpphase the cuff. The device inflates the cuff does not automatically to 200 mmHg or more, but only as far as necessary. Especially my father, who has to measure the blood pressure several times a day, this is perceived as very pleasant, because the cuff pressure is not as strong as usual at the doctor. I highly recommend this device on.
