"Machine is playable but in rough condition. The three drop targets on right do NOT come up. The full plunge sends the ball straight down the middle. Playfield is filthy. Left flipper sticks up. Costs 6.4 credits per game" Black Knight: Sword of Rage (Pro) (Stern, 2019)
"Both right flippers intermittently get stuck, possible issue with the switch contacts in the flipper button sticking to each other. Multi-ball is effective for dislodging stuck flippers, but it happens quite frequently and at inconvenient moments." Iron Maiden: Legacy of the Beast (Pro) (Stern, 2018)
