Blackroll Booster Set Med Vibrates the tissue and promotes blood circulation - The Blackroll Booster Set Med consists of the vibration core booster and the fascia roller Med. The latter is made of water-insoluble, robust EPP and can be easily disinfected after training. Compared to the Blackroll Fascia Roller Standard, the Med version is 20 softer and therefore particularly suitable for slim and sensitive people, for sore muscles and other tensions, for cool-down and in the context of rehabilitation or therapy. The booster core also makes self-massage gentler with its high-frequency vibrations, as these confuse the pain receptors in the tissue. Spot massages with the booster are therefore also experienced as very pleasant. - Set components - 1 Blackroll Fascia Roller Med - 1 Blackroll Booster - 1 Micro-USB charging cable - 1 exercise card - 1 booklet with operating instructions - Product details Booster - Input 220-230 V, 5060 Hz - Output power supply 5 V 1,000 mA - Max. power consumption 45 W - Lithium-ion battery.
