FENLI’s electric massager for shoulder pain is engineered specifically to alleviate upper body pain through therapeutic mechanical action. Featuring asymmetrical 3D Shiatsu nodes driven by high-torque copper motors, the device applies targeted acupressure deep into subscapular, rhomboid, and trapezius muscle groups. Integrated carbon-fiber heating arrays project 42°C infrared warmth directly into tight tissue, increasing localized blood flow and speeding the removal of pain-inducing metabolic waste. The ergonomic frame drapes securely over shoulders, utilizing adjustable arm straps so users can control therapeutic pressure depth. Manufactured in FENLI’s ISO9001 certified facility with CE, RoHS, and FDA listings, this device offers healthcare vendors and retail brands a certified, pain-focused massager engineered for optimal therapeutic effectiveness.
