Collapsible Silicone Steamer 5 "Excellent item." Keith Cross 10 September 2019 Easy to use, easy to clean, easy to store. I have made casseroles in this & have steamed fish & vegetables. I had to check the food I was cooking at intervals so I didn't over or undercooked it, but it was simple to work out the timings. The lid fits on easily & stays put, & the steamer does not collapse when in the microwave. It's a great time-saver if I don't feel like cooking a casserole slowly on the stovetop or in the oven, or don't have the time. Very pleased with it.
