Product review (1 stars): Don't buy! Always looks dirty.
They look great and conform well, HOWEVER the silicon is tacky and catches and holds every piece of dust or spatter. The only way to make it look good is to wash in hot soapy water, drip dry and avoid handling the topside when placing. Oh, and don't cook. Because we were busy with a family reunion we used them. It has been several weeks now and we were hoping they would lose some of thier tackiness, but that has not happened. Waste of money.
