Is this like an experience I have been through? Yes. Several times. Does it surprise me? No.
I ponder this question: What is the the minimum price set by pen manufacturers for a product forcibly undergoing human examination and testing before leaving the factory?
Honestly that doesn't matter in my opinion. What one person expects from a pen will vary from one person to another. I've gotten several pens that were claimed to be human tested and tweaked before they leave the shop and as of now I still haven't gotten a pen that writes well enough for me where I don't have a hand in adjusting it myself. This includes nibs coming from nibmeisters. Sure, there are times when nibs are close to the point where I think about not touching them, but then something just nags at me as I'm writing and eventually they get tuned. I used my Pelikan M600 for over a year after some slight tine alignment and it wrote well enough but a few weeks ago I really sat down and adjusted it because after all this time there was still something about the feel of the nib that was bothering me.
I've read so many reviews where people claim pens write perfectly and buttery smooth. At first I thought that maybe I just had bad luck but as I've acquired more and more pens I've finally decided that my standards for how my nibs should feel is just different from others. I recently bought a Levenger True Writer as a gift for a friend's birthday. I spent close to an hour adjusting the flow, alignment, and changing the sweet spot and smoothness of the nib to where I was happy. I doubt any company is going to hire someone to sit for a straight hour adjusting one pen.
