I had a puck of the Fat back when I first started shaving. I sold it off after having some trouble with it (very possibly/likely user error). One day I might get back to it to see what my experience would be: I've got a lot of soaps to get through first. That, and I discovered Haslinger's Schafmilch, which did what MWF seems to be reported to do but I had no trouble lathering it.
