What are the advantages of the KY1081 three-in-one massager compared to single-part massage devices?

It saves costs by being multi-functional, eliminating the need to purchase separate devices for the shoulders and neck, knees, and hip bones. The functional modules are optimized for the characteristics of different joints (for example, focusing on red light repair for knees and enhancing air pressure kneading for shoulders), offering a much higher cost-performance ratio than purchasing multiple single devices.
