I've had my Le Creuset for 32 years. My mother bought it for me when I got my first apartment. My only complaint (after all these years) is that when I use the lasagna pan, it is really heavy to lift out of the oven (in my dream kitchen, I want a built in oven...it's coming, slowly but surely). I refresh the "seasoning" regularly. I had an accident with my 8-qt pot recently...the beets boiled dry. I tried baking soda, it helped but didn't get rid of the stain. I went on line, and learned that one can pour bleach in the pan, bring to a low boil, let it sit overnight. It worked beautifully. It is in the oven reseasoning as I write this.
My brother also has a set of Le Creuset. I saw a "blurb" on TV recently that Le Creuset is the "sexist" cookware.
When my mother gave it to me (she added extra pans that weren't part of the set), she told me that it would last me my lifetime. She was right--it has made many moves with me and I wouldn't dream of replacing it. The only reason I'd stop using it is if I get too feeble to lift the pans.
