Seriously. This is my favorite black ink I own - it works with all my stamps, and even makes some of them look crisp where they were mushy, clean where they were sort of munged. It *does* require special cleaner to take it off which I have only used on my rubber stamps, not my acrylic ones, but it's worth it in my opinion. And I love the smell... I can't put my finger on it, but something about Black Staz-on Scent just makes me hungry, though I certainly wouldn't encourage ink sniffing. ;) I actually like my black better than my Olive Green, but the Green isn't bad either. I also like that it dries incredibly fast on regular papers, meaning I have less of a likelihood of smearing it all over the place. Bad for embossing, good for clumsy!
