My thoughts, based on a small sample:
A tallow soap from a British artisan? I was in. In fact I'd been meaning to take a look at these for a while.
I found lathering took some effort, although subsequently I see they note that their soaps are ‘thirsty beasts' — which would explain why I got better performance when blooming it before use. With a bit of water lather blossomed.
Slickness and protection varied and I rarely got away without a good number of nicks. Few were substantial but were more than I'd expect from a soap providing adequate protection.
The fragrance generally accompanied me. It's described as tobacco, leather and juniper. I picked it up as a ‘soap' scent more often than not but paying closer attention I may have confused that with the tobacco (or it's layered on top, just not very strong). It's pleasant enough but didn't do much for me.
I've heard a lot of good things about these soaps, so my experience may be down to using a sample rather than the main product.
That said, I found it did a pretty good job with enough water. I'd describe it as competent rather than stellar though.
Full review here.
