Beware! Cast Iron became extremely rusty in first use! Bad customer service! I didn't want to buy a Cast Iron dish of low quality and this seemed to be a good one. But just when using it for the first time it became covered with heavy rust. I got a replacement, took it from the box, and following the instructions carefully I gently washed it, oiled it and started cooking. When opening the lid I found it again cover with rust. Trying to communicate with the manufacturer's customer service - they refused to take responsibility and said that I used it wrongly. No product, cheap quality as it will be, is not supposed to have rust all over in first use!!!
