This Rubbermaid casserole dish is awesome. It cooks well and cleans well. Dishwasher, Microwave and Oven safe, a triple threat in the kitchen. My only complaint and the reason I gave it 4 stars instead of 5, is because the lid stains. I have washed it several times in the dishwasher and I hand washed it but there is a discoloration from red gravy. Other than that, it is a perfect addition to my kitchen.
