Product review (5 stars): This will save you a lot of cleaning and frustration!
A must have in any kitchen with electric coils. This saves me so much cleaning (for those who are lazy and clean only to make things look nice, it's nice not to notice that your bowls are rusting or have burnt stuff stuck on them since the black parts just blend right in with the black porcelain bowls). Now, instead of having to clean the bowls after every cooking event, I can clean once a week and still have it look fine). Also, the lack of rust is worth buying these extra bowls. You can put the regular (hopefully still new) silver bowls back in before you move out so it looks new for the new people who are moving in next.
