The whole discussion whether oven rack yes or no I can only say .... my parents do not have one, and promptly packed our little slice of the oven (at home could not have happen) and to burn their fingers. Since all caution uses sometimes nothing. Above all, the oven most dangerous when it is not even hot outside and only the disk was already heated. So Sohnemann has nothing of a hot stove noticed (who has still emitted no heat) and kicking gepatscht on the disc. We lucked out and he has suffered no major burns.
But you have to end all decide! For my part I can only say that if you're looking for a solid, high-quality oven grid, this is the right place.
