we are remodeling our kitchen, so I bought this burner to help while I have no stove. I didn't like the control knob right from the beginning. However, after less than 10 uses, the entire unit stopped working. As I only paid $12 something for it, I threw it away. I am currently using a Cook's hot plate that not only cost less, but is sturdier with a better control mechanism. Don't waste your money on the Proctor-Silex Fifth burner.
