When pen arrived, it didn't wrote well. It has skipped. Bad starter. Flow was great, so it was almost impossible to use PR inks. Pen did not hold a lot of ink. I have contacted Omas service department with mixed results. Thanks to some fellow forum members and Sam from Pendemium I got enough information to press Omas to repair it.
I agree with Noble remarks of springness of the nib. I would call that "luxury feeling".
I have sent pen to Bologna, telling them that if they are going to replace the nib, I would prefer the stub nib.

Two weeks later, this is what I got.
Springiness has gone, but now I have wide (around 1,3 mm) stub nib with great line variation.
Celluloid is great. On one side there is great colour variation from vanilla to deep brown, on other sides there is less variation. (Photos are usually showing just side with biggest colour variations.)
Nib has great design. It has inspired me to buy Pinstripe Duofold.
Pen is quite light.
It holds ton of ink. Earlier remark is linked to internal error of Omas pens that are couple years old.

For some strange reasons, this nib doesn't work well with regular inks like Omas, Diamine or Herbin. It works best with Noodler, Private Reserve inks and Waterman Violet ink. With those inks, pen is writting really well. With other inks, nib doesn't start well.

I would never pay list price, but everytime I take a look of celluloid, I apreciate its beauty. This pen was bought to be daily writter, but I have decided not to take it out of my home.
All in all, here is my vote(after repair):
Finish: 5 nibs
Look: 5 nibs
Filling: 5 nibs
Writting: 4,5 nibs (5 with Waterman Violet, 1 with Herbin ink)
Cost: 4,5 nibs
