This allows for various applications, especially for tight muscles and painful hotspots and knots. Deep tissue massage, spot-specific massage and shearing treatments are possible. The different degrees of hardness combined with the BOOSTER'S continuously adjustable vibrations ensure that the most beneficial intensity can be used in each treatment.
