Product review (3 stars): About what you'd expect.
You know, they're discs of metal. Not a whole lot to say. Kinda cheap but I'm not scrambling eggs on them so who cares? We put them over the stove in our guest house so the moths and other bugs don't get down in the stove when not in use. The sizes aren't perfect for me but that's no fault of the manufacturer. If you just want to keep bugs out our grease off your burners, these will do it.
