What can I say ...I bought this product in hope of easing the pain in my knees while waiting for a knee replacement . I am a full time carer for my wife who has Huntington's disease . All i can say is wow , honestly for the first time in a number of years , I have no pain . Obviously doesnt fix my knees but it means with a strap ,I can walk pain free which is amazing . I have told shared and recommended your product to anyone who will listen . This is my second order and I will be ordering again . Thank you guys for such an amazing product .
