The only issues I have had have been with ACDC and have being sorted quickly by Stern
Bell opto failed - fixed in 3 days
Cannon ball stuck - I added PinballLife mylar to base and side and smoothed ball entry -works A1!
Dent on playfield and 1inch clearcoat reduced by rubbing back to reduce damage - New playfield on its way - Hard to notice!
Hologram sticker doesnt match up with build no. - ?
Overall Stern build quality has been great with very minimal breakdowns!
I had 5 B/W A titles and was always fixing things
