Eternal Ink...

hey- Hoping some of you can tell me if Eternal ink is good ink- I went to the MA convention this past weekend (had a great time!) and purchased some Eternal Ink - I just bought one bottle to try it out, Triple Black its called. I used it on Sunday on one of my clients who I am doing a large forearm piece and it was good as far as getting in etc---but was wondering what I can expect for longevity. Normally I use Starbright and a few Intenze colors but this is my first time using Eternal. I know there is sometimes debates on inks and mfg- and I am wary as this is a company I am not familiar with but who I have heard of in passing. Thanks!

I use some of the colors in my shop. They are a good brand. Personally I think just the black outlining ink is some of the best black available as far as ease to work with and the way it holds its color. So I use that black when I dont want the mess that Kuro Sumi leaves. Great black but makes a mess when shading a large piece. The only other colors I use is the earth tone set.
