Unfortunately this disc (Original Cullmann Nr.40470 in original packaging) is produced too imprecise and thus has on all sides about 0.5-1mm game, making it unusable!
Pride sticks to the plate a small sticker with 'Dt. Engineering, Made in China 'and that is probably the cause.
Cheap produces and sells to dt. Prices, without proper quality control.
Conclusion, Cullmann is no longer purchased from me.
