I read a thread on Facebook that a USA purchaser of a KISS pro kept complaining about the alinement Gene's head causing the ball to drain down the middle. After giving instructions to the owner several times to level the machine and rotate Gene's head, the person allegedly couldn't' get the ball to not drain. Stern gave him a full refund, even though in my opinion it wasn't warranted!
So better a company that warrants their product beyond their started warranty, than a company that provides great warranty but needs to be taken to court to follow through.
but even better would be a company that tests a game before releasing it to the public
I sometimes wonder how much play they give a whitewood before they put it into production
