This professional massage gun features five adjustable speed levels, with a revolving speed ranging from 1200 to 3200 RPM, and includes five interchangeable massage heads to meet the needs of different body parts. It is designed for sports lovers and anyone seeking deep muscle relief, offering a 12mm amplitude that deeply strikes muscle tissue to help relax your body without hand shaking, even at the highest speed. The massage gun uses a high-quality brushless motor that operates at less than 45 decibels—quieter than normal speaking volume—while providing an extra-long endurance of up to 20 days on a single charge (based on typical usage). Whether you are an athlete recovering after training, an office worker relieving tension, or anyone dealing with sore muscles, this quiet, powerful, and long-lasting device delivers professional-grade percussion massage wherever you need it.
