Nice BIG enameled cast iron dutch oven. like LeCreuset but costs less
Color: Blue, Size: 6-Quart
This is nice quality, similar to the far more costly French LeCreuset brand. I was surprised how big this model is, possibly too big for my small kitchen and limited storage space. I store it in the oven. It would be great for baking sourdough boule bread.

Enamel finish
Color: Matte Navy, Size: 6-Quart
This is an amazing pot, got the 6 Qt for beautiful roast dinners and for baking bread. All comes out evenly baked. Cast Iron is best and it has a nice finish for easy clean up.

Great quality. Easy to clean. Nice appearance.
Color: Red, Size: 4.3-Quart
Solid, heavy pot for cooking and baking. I bought it mainly for making soups, stews and breads. I have only tried soups thus far. The pot cleaned up very easily. The bottom of the pot heated uniformly. Nothing was stuck to the pot when I was simmering on the glass top stove. I have not had the chance to bake yet, but seeing how evenly it held heat while cooking, I am thinking this will be perfect. I bought the red color. It gives a nice pop of color in my kitchen. This pot will probably last me a long time. I would buy one if I needed a replacement, or a gift for someone.

Great quality for price after 3 years of use
Color: Matte Navy, Size: 6-Quart, Color: Matte Navy, Size: 6-Quart
I’m 3.5 years in and use it weekly. So far it’s been a great product especially for the price. We are really into soups, roast, and I bake bread a lot. This thing is amazing and a great quality. It’s easy to clean, does great in the oven, and stands up great to constant use. I only have a small amount of staining at the bottom, and a couple scratches from metal utensils. The lid is solid and the handle is really secure still, which is a problem I’ve had with other brands I’ve tried.
