Are LAMY replacement nibs tested at the factory?

[Skydiver]

I've learned that LAMY pens are tested at the factory as part of the quality control, but are the replacement nibs also tested at the factory? I'm a little bit concerned by the recurring theme of scratchy or non-functional replacement nibs in the 1 and 2 star reviews of the LAMY replacement nibs at Goulet Pens:

Or are all the "bad" nibs just clustered on a set of production years and it has gotten better since then?

In my limited experience, the nibs that came mounted on pens are generally decent, but the nibs bought separately (except the gold versions) are sent to the resellers in bulk with limited packaging, and these could often use some adjustments upon receipt.

 

That said, I recommend buying a Z52 or Z53 over the Z50, as I've had more luck with these right out of the box.

I also noticed that the Z50 I got recently were better than those bought 15 ish years ago.

Never had issues with replacement Z50 nibs so far.

I have 4 spare Lamy Z50 nibs. One M and one EF are outstanding. A 1.1 is good, but needed some smoothing to remove a roughness from the slit end. Finally, um M came out defective, but not because of the type - it did not write badly, although the tines were closed and I had to separate them - but because it must have fallen badly in the machine that folds the sheet and it was asymmetrical. I had to insert it very carefully to get it aligned, so I decided to buy another one.

I've heard that the nibs have improved lately. However, the last M I bought is pre-2020 (it has a burn mark next to the breathing hole) and is excellent. The newer ones are all very good. I have 13 nibs in total, 4 rubber disc cut, pre-2020, and 9 laser cut, the newer ones.
Only two are defective, both pre-2020. The M I talked about earlier and an F that had a burr on the slit. After removing it, it went on to write just fine.

Such I'd send back to the factory...and get a free replacement. Lamy and Cross are the only factory's with 'life' time warrenttees.

Thank you for your advice. Yes, I have read very positive comments about Lamy on the Penexchange forum. The problem is that with something so cheap, it doesn't make up for the expense of shipping. Now there is a Lamy Brazil, you could give it a try. Yes I will resort to that warranty if the liner cap breaks. Although the Safari's are cheap, I don't like having to throw away a pen that is fine because of a liner cap.
