Looks great -- I really love the look of the bronze nib! The barrel is round (as opposed to the faceted sides of the TWSBI AL) which makes it feel less stable (?) when holding. Build quality seems very good and ink capacity is phenomenal.

The main gripe I have is with the nib. It's very broad, wider than a medium Lamy. It also seems to skip when not enough pressure is applied. Maybe a fine nib would have suited me more but you cannot change the nibs on the ECOs :(

Excellent pen!

Beautiful pen which writes very lovely

I love my TWSBI pens and this one is no exception. The filling mechanism works wonderfully, and it writes like a pen twice (or three times) the price.
