Do not impact the joints: The fascia relaxation gun is generally only suitable for dry muscle and soft tissue. If you directly impact the joint, it is almost the same as knocking the joint directly on the stone. It is easy to cause joint damage. 3. Not all parts are suitable for use: Muscles such as the neck, chest, abdomen, and axilla are thinner, and near the organs and aorta, fascia guns are not recommended at all. 4. Not the longer the time, the more painful the more effective: Use the body to sense the soreness that is maintained at 6-8 minutes, and use the same place as long as possible within 1 minute. 5. Do not use for infants, young children, pregnant women, those who wear pacemakers, fractures or have metal contents in their bodies." 6-speed speed control designFour kinds of massage head7.4V brushless motor technologyIndependent power management systemVibration principle hammering style
