Review on KPKitchen Set of Silicone Baking Mats by Gregory Shin

These rugs are definitely not high quality. They developed black charred patches on exposed areas when first used (there was no food on them) and no cleaning will remove them. This has happened to two so far. My other silicone mats have never done this. This brand is not very good and I will never buy anything from this company again. This is the second product I've bought from this brand and unfortunately I didn't notice it. I would try to return them but I have already thrown away the packaging.
