Query: Plastic on a stovetop??!!!

The egg cups are 100% plastic. Why would the manufacturer make a stovetop item out of plastic? This simply doesn't work. The plastic cups eventually melted. The eggs stick to the plastic. Please save your money. Williams-Sonoma sells a quality poacher with metal, nonstick cups. It's well worth paying a little more for something that will last.
