Query: Nasty smell, doesn't cook very well

We bought one to cook brownies. We have used it twice. Both times the smell in the house was like burning rubber. Very harsh. The brownies did not cook very well. They did not cook as well as they do in traditional pans. I had to give this away. I't give it zero stars if that were available since it is unusable. I also did notice that it did not clean very well, but that was the least of our problems.
