Relief from rib cage pain

I have been using the mat (5-therapy Classic 74" x 28") for four months (purchased last November 2021) and have noticed the following.

1. I wore a knee brace for over a year to go walking, but after three months on using your mat, I no longer needed a brace and my knee is totally pain free.

2. I have an extremely painful rib cage and the PEMF and red light therapy got rid of the pain in three days when I did three 1-hour session each day. My husband was very impressed and we're now doing the same treatment with his shoulder.
