When I saw this on tv, I talked to my doctor and got it. First try I could tell an improvement and it help me walk with low pain and sitting. About a month later, I had showed my doctors how it saved me from a lot of pain I had before. I go out for over 4-6 hours and wear it so it helps me through the day. I’ve learned to bring the name and number of this product, for I’ve had a lot of people ask me about it everywhere. This helped my chronic pain on mid back and lower back a lot. Thanks so much!
