Product review (2 stars): OK for a while, I guess
These are not "universal".  My electric burners rest on top of these rather than inside of them, so my burner covers hover like space ships and look pretty strange.  They are not a good fit at all, but they will do until these get nasty looking and need replacing too.

I will not recommend these because of the strange fit.  The quality is actually good.  It's just the fit that's off.
