dfk41 well, I can certainly see the meditation is working, Dave. :D
This was originally a commissioned product, sought after by someone who wasn’t happy with the stock clip and screen (who am I to argue with them for that?). Now it’s being offered to others who may want it, perhaps for similar reasons, perhaps for others.
It is fairly obvious the price excludes die-hard skeptics, leaving those with disposable income or a purpose they can justify to themselves - could be that some people care about the stock screen and spring not fitting well enough for good wetting of the puck - I’ve had nasty lop-sided extractions occur in that situation, and I don’t enjoy messing around with the circlip (something Jake also mentioned). I’d like it to experiment with it, and will happily run with it if it makes my life a bit easier on the maintenance front.
