These are just great oven mitts. Unlike more traditional mitts, these don't get dirty or wear out and if you get something on them they are easy to clean off. Construction seems pretty good, the grip is great, and no heat transfers through the glove. I've used them with lots, pans/skillets, pizza trays, casserole dishes, bowls, and all manner of materials including cast iron, stainless steel, glass, and ceramic/clay. An all around great product. I'm a convert - no more cloth mitts for me!
