Own RRWOZ, Hobbit LE, and JJPOTC LE. Never had a single issue. All playfields are pristine, no chips, etc. All mechs work with no issues out of box (or trade in regards to my WOZ). Only had to replace 1 spring on one drop target on my Hobbit. Play 'em weekly. From what I can tell no more issues with their games than any other manufacturer.
