If the device is applied properly to a previous personal dormancy on the left arm, one obtains rather precise information. This will allow me to evaluate my values and tabellisieren. Along with the prescribed medication from my doctor, I can say that my high blood pressure now normalized. Without the Geräüt I would ever go to the doctor "chug", but that we do now with the help of Sanitas SBM 21 only once a month.
I am very happy, but can not give any indication for simultaneous use by multiple people, but their separate data storage is probably no problem.
