There's also a widespread problem of counterfeit Lamy Safaris out there, which usually come in subtly different packaging and/or have subtly different markings on the pen body. These are widely considered to be inferior, and fairly common if ordering somewhere like Amazon.
I routinely work under a high-magnification dissecting scope to build experimental equipment for neuroscience, but I never considered that people would be doing this to optimized their writing instruments.
I think many people get drawn into the hobby for the endless pursuit of matching pens, papers, and inks, or trying to optimize for various characteristics across different combinations of the above. Of course a lot of people don't bother and just find one that works well enough and leave it at that.
Even the gold nib needed tuning. :(
You should be able to feel a _consistent_ feedback as you write with a proper nib. Two of the three nibs that I bought didn't perform out of the box. And a fine nib was too dry. I bought some brass spacers to separate the tins a bit.
Amazon? IME, more commonly bad batches.
Small independent retailers who live and die by satisfying their niche enthusiast customers? Yeah, they're fantastic, and they're generally passionate about what they sell.
If you buy from eBay or used elsewhere or for that matter Amazon, you do sometimes get a bad nib because someone has tried to tune one of these nibs and botched it and then decided to try and sell the pen new.
It feels like a rolling ball with a nib, and that pen was my go to pen for a long time before the Pentel EnerGel replaced it.

I've been using this pen for a long time and I just love it so much.
