Exactly as expected - great!
I'm using this in a TWSBI eco for note taking in my college lectures. It has a great 'green-black' color that looks professional, but with just a bit of flair of personality. I'm left-handed, and this doesn't dry quite as quickly as the kon-peki I've used before, but still dries quickly enough that I haven't had any of the dreaded 'southpaw palm smear'. I highly recommend Iroshizuku inks, and this is a wonderful color from them!
