Whats not to understand? The OP got a lemon, a defective product, a bad apple. They shouldnt have to pay any more to get it repaired or replaced because they have already paid for a working product but didnt get it.
If you ordered shoes by mail and got a box of rocks youd have a right to get upset about it. You shouldnt have to pay to return the rocks and get your shoes.
This does not mean that your copies of the same product are somehow bad or defective. If yours work be happy. But your good experience with a product does not invalidate someone elses bad experience.
Different situations. OP was not sent the wrong product. THAT would be perfectly acceptable to demand an exchange at no cost from the company it was purchased from. If the product was defective when received, the vendor is the one who should be remedying the problem. If they bought it directly from TWSBI via their website or amazon, then yes, it's a crappy thing for them to not replace the product completely, as this is post sale support, not warranty support. I'd be upset about that.
But it sounds like the seller offered to send a new nib, which is a less than perfect situation but very common and generally not an issue unless it's for a pen with a notoriously fragile feed like the 580, but the "can't guarantee perfection" thing is just obvious. QC failing happen. There's no way to avoid that. I have gotten two dud nibs from visconti in a row, on a pen costing thirty times as much. that's inexcusable.
If the OP was uncomfortable exchanging nibs, they should tell the seller that, and ask that they be provided a return label so that the seller can exchange the nib for them or give them a new pen. Goulet would do this. If they won't do that, again, good reason to be upset, but not at TWSBI.
If the OP bought from jetpens, they will screw you over if you send them back a product and they "can't replicate the fault", they'll ban you forever from buying a product from that brand.
Again, this sounds like a mild annoyance in an otherwise solid experience with the brand. I feel bad for the OP, but I would also warn them that this experience with "pay for shipping to the company for warranty work or shipping for the replacement part sent" is the experience they can expect from nearly every single company, so generally, just buy from good vendors who will take care of you for 90 days like vanness, goulet, etc.
