Product review (5 stars): It fits properly, and it works!
As of now, I can only say I like it because I tested it, made sure it indeed fit my stove, and worked properly, then let it cool, reboxed it and put it away until canning season! Perhaps I will come back and update once I've been able to do more than verify that it works.

Update 08/22/16:
This burner works wonderfully! Used it for my entire canning season, and it kept my pot elevated, and my stove top from burning like the heat of 1000 suns. I am very happy with this purchase, as is my stove!
