i believe it does work,
I tried this hoping to see if it would help with my Rheumatoid arthritis I was waiting on new meds for I hadn't had anything in 3 months and was desperate to try anything. i heard copper bracelets and was like eh idk. but i am a believer now for i wore it for a few days and i could tell a difference if i don't wear it. i am now finally on meds that are working so i don't need it but i still keep it as a back up :)  it did for me improved it anyways it was bearable and my morning stiffness wasn't near as bad.
