No sir, no complaints here either.
Once ordered a dome from them and the next day they called me to let me know that while they only had one left it had a pin hole in the plastic when it was made and if I still wanted it (even email me pictures of it) - told them sure as I wasn't too concerned. Then I get another call from them the next day to let me know that they just got a new shipment in and would be sending me one of those instead. So yes, excellent customer service.
But then, I can say I have had great service from the other dealers I have bought from as well (including Pinball Life).
