I had a little fear about some negative comments on the results of this blood pressure. However, I was pleasantly surprised by the accuracy of the results compared to a professional monitor. Just simply follow the advice of use, ie be calm and sitting or lying feet to the ground, do not move during the measurement, and have the device positioned at the same level as the heart, and the measurements are reliable, including measuring heartbeats In summary, good consumer product, easy to read and easy to use
