So, it looks like you can do a low and slow cook in the warmer if you are doing a hot and fast cook in the main chamber; otherwise, it really is just a warmer. I think I'll just keep hold cooked meats in a cooler covered with towels like I have been doing, or buy a cambro or two. Paying for a non-portable warmer that you can't really cook in is not worth it to me.
