I have a black glass top with rings. The rings are under the glass not on top of the glass. I use my usual pots but I did have to get rid of a few that wobbled. No idea why they are there but being black it doesn't bother me. The thing that does bother me is my fridge won't hold a 2 liter coke or a gallon milk jug anywhere but the narrow door shelf. Next fridge, I am taking in an empty bottle and testing it before I purchase.
