The cervical vertebrae massager works by applying a synchronous multi-channel circular traction massage from an efficient compound energy field, this energy directly reaches the collective deep tissue and the bone marrow. The daily load on the neck and shoulder muscles, if not dissipated, causes symptoms such as neck fatigue, numbness of the arms and shoulders, headaches, symptoms of dizziness. This multi-channel massage improves local blood circulation and relaxes the muscles, thus achieving anti-inflammatory, analgesic and fatigue-relieving effects. The low-frequency electric pulse, magnetic effect and synchronous circular traction massage form a highly efficient composite energy field. With the latest 3D intelligent adjustment technology, the electrodes can be easily adjusted according to the curve of your neck, making them more comfortable to use with external wiring. There are 2 automatically combined massage modes, 4 manual massage modes, which can be selected according to diffe
