    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.

    Quality product
    Color: Navy, Size: 6-Quart
    I absolutely LOVE my Dutch oven! The reduced cooking time for certain cuts of meat for stews, pot roast, etc., is a definite game changer!! The meat comes out so juicy and tender. I made curry and did the "burning" of the curry and was hesitant because I didn't want the pot to be stained. There were no stains left at all. I've used it numerous times since purchasing and it still looks new. It's very durable and the color is beautiful. If you're looking for a functional, quality, and durable Dutch oven without breaking the bank, this is it! I highly recommend.
