It's like magic!
Rezblock really works! At first I was kind of hesitant to use it thinking it's not gonna work. Holy moly, it works like a charm. It does exactly what it says it does. My water pipe has never been cleaner, I don't know how I lived without this product for so long. Although now I'm kind of OCD about it and I want it clean all the time. Buy it, it's worth it!
