"Watch the heat!"
Thought this would be a good product, but found it difficult to get the lid in exactly the right place. Because of that it was a nuisance to check if food cooked and then get the lid back right once I'd found the right place! Also, pay great attention to the fact that you can cook with less heat. I didn't and had a very dirty hob to clean afterwards due to water overflowing before I realised it was going to happen. All in all I wouldn't recommend this product.
