Product review (5 stars): ... my old (70's vintage) stove and it now cooks like it was new
I installed it on my old (70's vintage) stove and it now cooks like it was new.  The old one only got red on perhaps 8" of the coil, this one goes all the way around and makes a much bigger difference than I expected.  Worth every penny, and sooo much cheaper than a stove.
