I bought one for myself, which was pretty okay. So I bought another one for my cousin; however the second one had some unusual cracks on the edge of guasha and on the handle of the jay roller. I immediately returned this ?faulty product. Still waiting for here good news from Amazon whether I could get a full refund or not. Since the price is reasonable, I ordered another one which turned out okay. The delivery was super fast as well only 1 day.
