Quoted from Pinball-Obsessed:
I’ve never had one issue on mine and there’s 800+ Games on my machine.
Hope I didn’t just jinx it.
after about 10 games, mine finally starting having issues. Ball got stuck a few times, so I bent the end down slightly.. now it's a crapshoot between rolling back to the 3rd flipper and going all the way around the orbit shot. I'm tempted to cut the end of the rail slightly (and bend the loop down slightly) so it both has plenty of space to fall down, but also guarantees it bounces against a wall to slow it down. My only concern is that once I make any cut, it'll expose bare steel which means either I attempt to paint the end the same color as the powdercoat, or have it re-powder coated (which doesn't seem to be worth the cost).
Worst case I have the pinball life shooter mod as backup.
