Never have tried it personally. But, I have seen the guy at the pro shop have 3 of them he uses and he charges if people want their ball to hook again. I have rather new equipment at the moment, so I have no need to purchase the product. And I'm really anal about cleaning my equipment. Haven't lost any hook as of yet, but once I do, and if soaking doesn't work I plan on ordering this when I need it. Glad to hear it works good.
