Yep it's cack. It smells ok but if you warm it before use it just melts and its a pain to load a brush with and making a lather out or it is a pain, it does not like being moulded into a shaving mug it won't stick so it just spins in the top of the mug. I just put it back in the pot and it's now in the man draw.
I will not be buying it again unless they reformulate.
I used to use the black tub back in the 1990s. I haven't used the blue tub, but it has coconut in its formulation, and I may try it one day to see what it is like.
Give it a good soak and work the brush into it hard so that you get lots of product on. It's quite strong scented and an ok soap to use as a change, but not an everydayer for me. There are better cheap soaps out there.
