This sphygmomanometer decreases blood pressure over an upper arm cuff. The device looks with value and carries out his work so far without problems. Schön is the record of each 30 data for 2 independent persons, as well as the function of a guest measurement is not stored. Certainly, there are devices on the market with more gimmicks, I consider the integrated here in this model opportunities for adequate and meaningful. Therefore, I speak from a buy rating.
