As a 275 pound bicycle nut I have used COPPER FIT for ankles, wrists and left knee. Absolutely no help for my arthritis whatsoever was noticed. The products were poor fitting at hands and the ankle support slipped as I pedaled and not because of incorrect sizing. The copper infusion is a sales only ploy and the only products that worked correctly were my prescription for elbow and ankle and hand wrist. After corrective surgery I no longer need those unless gym training on cables...
Bottom Line: No, I would not recommend this to a friend
