This item is a true answer to my prayers for relief from sciatica pain that I have dealt with unsatisfactorily for over 37 years!As soon as I put the device on as instructed, the pain goes COMPLETELY away! When I take it off the pain comes back, but while wearing it the pain is ALMOST non-exist-ant!No drug, therapy, or plain time passed has helped with the sciatica pain which I have suffered with for decades like this device.A true blessing!
