Reconditioning Must-Have

"I’m a physician, and I am so appreciative of how much KAATSU enabled my disabled daughter to recondition after a prolonged bed-ridden phase."

Great for Post-Surgery

"I started using the arm AirBands 7 days after my wrist surgery for 6 weeks. My wrist healed remarkably well and quickly. My surgeon was very impressed with my healing and progress."
