Thank you for viewing. This product allows for care by generating microcurrents. It doesn't require any force to use. You can care for yourself by gently rolling it while generating microcurrents. It comes with a solar panel, so charging is not necessary. Just expose it to sunlight. *Microcurrents are "weak electrical currents" at the same level as the bioelectric current that naturally flows through the human body, which enhances the body's natural healing ability by applying it to the affected area.
