does not smell unpleasant
pleasantly quiet
Heat only to the "fingers", so no general irradiation of the neck.
does not knock (!) but revolves with 4 fingers.
The fingers are barely cushioned and hard as nails in itself. So if you (see below) the positioning hinbekommt not clean, kanns also hurt.
processed wertig
Loops pleasant and big enough arms to mount.
simply lean work when back high enough. However, the exact positioning of the height and the uniform hard proof of 4 long fingers is not easy.
I have the impression that all 4 fingers fix rather too high than too low. So at the top of the neck and top of the shoulder.
The head drauflegen lying goes with a corresponding number equalizing pads for embedding the device. Here too is the right positioning is not trivial, but doable.
During the operation there was only the selection slow or fast and with or without heating.
The massaged area is very limited. If one wants to also neighboring regions, in particular greater reach at the outer side of the neck, one needs yet another device. The same applies if you want to have additional knock.
