Product review (5 stars): Does a great job.
This is a great product if you have a microwave large enough to accommodate it.  It just fits in my microwave.  It does a fantastic job of steaming foods and has a large capacity.  I've fit several corn on the cobs in it and there was no unevenness.  3 pieces, no construction involved, cleans in the dishwasher.  I'm very happy with my purchase.
