I had it, and it worked somewhat. I had terrible pain for 3 months, and now I'm still not much better after 10 months! It's very hard to find any negative views. Most are from clinics looking for business. It did work for one area, and it might be that my nerves are still trying to connect and causing the pain and weakness in my back and legs I'm scheduled for the minute man soon! Hopefully to get better. Ive had problems for over a year so that might be my problem.
