My experience with Noodler's inks has been largely positive. I use Purple Heart, Walnut, Black Swan (English & Australian), Forest Green, Dark Matter, Black, Burma Road Brown, Cayenne, Apache Sunset, Tiananmen, Widowmaker, and some others that I'm forgetting off the top of my head, on a regular basis.

The only issue I've ever had was with La Reine Mauve. It clogged every pen I tried it in, and it stained an Omas nib (that nib is still purple after two years and much scrubbing). I'm generally not a fan of the viscous eternal inks that smell like sharpies, though. The regular old "ordinary" inks (the ones without superhero properties) have been great.
