Depending on who you ask you are going to get different answers.
I have yet to have a problem with the ones I have made.
The Power point from PSI but the nib is ugly(well clunky, to me)
I have made the button click from Berea but WC handles Berea kits but I don't know which ones you have purchased.
I have madew and am using the "gel writer pro from PSI and it has been working fine.
Isuggest you return the one you bought at WoodCraft.Show them it doesn't work and dismantle it in front of them.Once you take a click apart it is toast.
I think it is a marketing thing from the mfgrs point of view.
"clicks" in todays society are considered "throw away pens" regardless of the materials they are made from and who makes them.
It is a shame.I have shown roller ball pens to some people who push down on the top of a baron and look at eithr end to see where the "wrting end" will come out.
Personally I think "blue collar workers" nurses, doctors, would be a good market for a high end click pen with upgrade platings and excellent mechanics.I guess the mfgrs think the stima of the click pen as a disposable pen is not a worthy market.
Perhaps it is our fault for not demanding one(as if they would listen)
One thing is for certain, a pen that could be dismantled for repair without ruining it would be nice.
