F21

Rapid Release Therapy fascia knife, innovating again! The massage head has undergone a brand-new upgrade, bidding farewell to single-point action. It adopts a blade-style design that combines point and surface contact, providing a wider contact range and more uniform force distribution, deeply relaxing fascia and muscles. With multi-level adjustment, it is suitable for various parts such as the shoulders, neck, waist, back, and limbs, making it applicable for both professional therapy clinics and home deep relaxation.

PRODUCT FEATURES

 

140x140

FPM-21 Medical Targeted Therapy Device

  • Deep, Powerful Massage. High-frequency vibration driven by a high-torque motor delivers penetrating, percussive force that reaches deep into the muscle, loosening tight fascia and relieving stubborn soreness more effectively than ordinary devices.
  • Smart, Precise Control. An intelligent chip governs every operation, with adjustable speed settings that let you fine-tune intensity — from gentle relaxation to deep-impact recovery — to suit each muscle group and moment.

 

Targeted Massage to Help You Relieve Stress

  • Upper-Body Relief. Effectively targets the arm muscles, chest and abdominal muscles, as well as the neck and lower-back muscles — the areas that hold the most tension from desk work, training and daily strain.
  • Long-Lasting Endurance. A high-capacity battery keeps you powered through full-body sessions without interruption, so your recovery routine is never cut short mid-way.

A Technological Breakthrough, Pioneered in China

  • Lower-Body & Hip Recovery. Covers the lower-limb muscles, hip muscles and foot muscles, helping to ease fatigue and stiffness after standing, walking or intense lower-body workouts.
  • Scar-Tissue Friendly. With its precision-targeted technology, it is especially well suited for treating scar tissue, promoting softness and improving tissue recovery in sensitive areas.
