How does this KY1081 massager achieve "three-in-one" ? Are there differences in massage modes for different body parts?

It adopts an adjustable Velcro strap + snap design. By changing the contact area with the strap, it can adapt to different joints. For the shoulders, it focuses on pneumatic kneading + vibration relaxation; for the hip bones, it emphasizes heat therapy for soothing; for the knees, it concentrates on red light therapy + pneumatic support. One device covers the needs of multiple body parts.
