I bought this as a replacement for one that came with my microwave. It does the job. It is opaque so I cannot see how food is cooking without removing lid. A bit disappointed.
This looks and works exactly like the steamer which came with our microwave and which we used daily until it finally broke. The only difference is that it is orange (we knew it was when we ordered it) which Jeeves might have described as "sudden". Personally I like it.
