I ordered both this unit and the "Medisana MNT tapping massage", and wanted to keep only one of them. When trying out, I then realized that it quasi wegzaubert my TENSION headaches, when I let knead the already vorgelockerten neck muscles until "Medisana MNT tapping massage" device the deep muscles loose and with this device. Since this combination of the two devices can not be beat. I keep both!
