Works better than expected
I've had a lot of pain in my arm recently and used these over the weekend when I couldn't get to the doctor or chiropractor, and they really helped dull the pain. They didn't last 12 hours for me as the package said. Probably more like 2-3, and they don't stick all that well either, but I'm glad I ordered them and have reordered to have some on hand in case of emergencies.
