I was disappointed at first use for my sponge cake strongly attached, and finished pieces. The second time I took the precaution to grease the plate; to do or not? I do not know! However it works. It is not as good as that of the mark D, but it is still much cheaper and bigger. To conclude, if it existed with an edge of 2 cm, I'll buy another still, because it is convenient for lots of different confections.
