"Die deutsche Qualität" is no longer in doubt and we are sure to have a serious and pro product ;-)
Cushion compact, quite heavy, efficient rotary ball and relaxing: be careful to position themselves so that the massaging motion is gentle and effective, if it hurts is that it is badly positioned.
Tested on the neck, lower back, back, legs: it was really a feeling of relaxation and relief of tense areas, although of course this does not cure the evil, it soothes and although it does not replace not a human massage, we can say that this cushion is far from a gimmick.
The only - for me it is often position the cushion correctly before turning it on, and not always easy to find the button to support: so often better first need to turn it on before positioning.
The heater option is great!
To adopt!
