The quality is excellent. The material is soft enough not to damage my expensive knives. Of course this means that one very quickly sees cuts in plastic. Who bothers to a glass cutting board should increase (of course not, the Dinger are Messervernichter). The size of the boards is sufficient, but perfect for them just to be able to still put in the dishwasher. The marks are a good idea, I disregard entirely and simply take out just any. By 4 feet slipping all on the worktop is not about what I think is great. And also not to blame is the color choice. A beautiful dark gray. Some companies felt that the kitchen must be colorful like a circus tent, I'd rather have it "monotonous".
