Product review (4 stars): Ok so far
These fit my Whirlpool stove, for the most part.  It's a little tricky to get the burners to seat down in correctly but once they're in, they're in.  They aren't shifting.  They are made from a thicker metal than what I used to buy at walmart but they are just a tiny bit smaller.  I'm interested to see how they hold up over time.
