Mine just came in, and I assume others are receiving theirs as well. Show your first scribbles with it, or just let us know your quick impression of it. This is my first TWSBI, and I'm impressed. I've handled an acquaintance's 580 and like that, too, but I feel the ECO holds its own. A nice piston filler that has a good, solid feel in my hand at a price competitive with other intro pens like the Lamy Safari or Pilot Prera. Writes smoothly out of the box, for me. I wouldn't hesitate to point my friends to this one.
