I have several Le Creuset pots and love them all. My husband bought me a tagine last summer for my birthday and I despise it. The base is so ridiculously small (1.5 qt capacity) that you can't fit much of anything in it. What a complete waste of money.
I actually called Le Creuset to give them some feedback and the customer service rep said, "Yeah...they do look really small". It's probably too much to hope for that they'd come out with a larger base that would fit the lid I already own.
Oh well, live and learn. Just thought I'd pass the warning on to others.
