I love the Rubbermaid duralite baking dish. I made greenbean casserole and covered until serving approximately  half an hour later. It stayed warm enough for serving without a warm up. The lid stays nice & snug. It's very easy to clean, no hard scraping to get leftover pieces off after warming up leftovers the next day. It's lightweight and cooks very smooth & evenly through the cooking process. I like how easy  it will be to pack & carry when traveling in the vehicle to an event.  I will definitely be purchasing various sizes to replace all the bulky, heavier dishes I have.  I've already recommended to my sister and cousin on Mother's day when I served my, "Casserole Casanova "
