Lakeland Round Silicone Microwave Casserole 5 "Round ones far superior to the oval ones that I also bought" 03 September 2018 I was delighted to find this light weight cookware as I can no longer hold my ceramic ones.Initially I was so happy with my 3 oval shaped ones, I bought two more round ones. The round ones have withstood the test of time - they are great. They hold their shape making them easy to transport food, easy to wash, don't stain and easy to store - and I can hold them. I am planning to replace the three oval ones as they have not been so successful. the lids no linger fit properly, so much so that they have fallen into the food in the pots and they are nowhere near as stable - quite disappointing.
