My stove is electric. There are a couple of pots in my kitchen that are wider than I like than the diameter of my largest hob. My hobs don't heat perfectly evenly. I am thinking of getting a copper heat diffuser to help spread the heat evenly and hopefully help improve my cooking experience. This is an example of what I'm considering:

This diffuser is 1/8-inch (.125-inch, 3.175mm thick) Any thoughts, especially from anyone who has used such a diffuser?
