I'm liking it. I haven't gotten a big cloud like I see on some YouTube videos, but I definately get visible vapor. I think I need my stuff to be a little drier, but it is working for me.
I agree that the stuff is fairly green after, although I think I am getting it a little browner now that I have some practice. Anyway, I look forward to putting it in my Volcano and jacking it up to 9 when I am low on the fresh stuff.
