Every NIB pin I've bought has had in warranty issues, and every manufacturer has been GREAT to deal with...at first. And then they got worse. And then became non-responsive.
I've had this problem with Stern (still waiting on that playfield promised almost two years ago).
I've had this problem with JJP.
I've had this problem with AP.
Ironically, Spooky was the only one that gave A++ service the entire time.
