In December 2016 I purchased a Shuzi Italian Band from a stall at Johnsonville Mall. It would have to be one of the best purchases I have ever made. Within a day the pain and stiffness in my thumbs that I wake up to every morning had all but vanished & the swelling has also gone. I had surgery on my knee a few years ago which left it swollen & painful. The swelling has gone down and the pain has greatly diminished. I would definitely recommend this product.
