Hello QiVantage,One week ago I applied your Chi treatment on my leg for approximately 12 hours. The next morning, the tightness and pain seemed to be gone. I ran with no pain and continue to do so over a week later.If I didn’t experience this, I would not have believed it. I am very happy with your product, and should I need to use it again, I would not hesitate. Thank you for your help, and customer support!
