Someone around me has used it, and my back pain hasn't healed for a long time before. I went to a health care project and felt better! In the process of experiencing magic, it can not only promote the friction and temperature rise of its own water molecules, but also change the body magnetic field to return to normal when it is heated from the inside out. This change will keep its own magnetic field effective for more than 72 hours after use. Still a good experience, you can try it! Recommended!
