It used to be great. Current stuff can make passable lather if you add glycerin to it or soak it for a very long time and keep it "muddy" when you load. It's not as bad as many people say, but it's not worth buying. Arko outperforms it without the hassle for about the same price, and I'm even a fan of arko.
The real shame of Williams is the vintage stuff is probably the best shaving soap ever made.
