Bests & Worsts Reviews from Amazon

This device gives completely inaccurate readings each time it is used. For accuracy, I checked my parents blood pressure manually using a sphygmomanometer and stethoscope. We then tested this device. While manual readings showed normal BP, the device kept displaying hypertension stage 2 readings. Proper instructions were followed and cuff was kept at heart level. Arm based battery powered BP cuffs are more reliable, but there are several wrist BP cuffs that will provide similar readings to arm ones. This just happens to not be one of them. Save your money and go for a different brand.
