The Eleels therapeutic massage gun is based on unparalleled technology and is a vibration device that improves circulation, alleviates muscle stiffness and soreness, prevents muscle damage, and reduces lactic acid levels. The Eleels X-Series percussion massage gun stands out from other massage devices. While others may use eccentric wheels to produce only weak vibrations, it employs a piston motor, similar to those used in vehicles, to create a shaft that penetrates deep into the muscle tissue due to its rapidly rotating motion. Recent studies have shown that percussion massage with a massage gun can cause muscle tissue to contract 30 times more strongly than normal voluntary contractions. Therefore, the Eleels device operates quietly and does not produce vibrations that fatigue your arms when held.
