Product review (4 stars): Decent product
UPDATING WITH PHOTOS - to show that it fits right on top of the burners.

It fits like a glove onto the Whirlpool range, no wobbling.  It's a bit on the thin side, so I did burn my first batch of pancakes, however, that's easily addressed over time.  Only four stars because it provides a really a very small surface area, much more narrow than my previous JennAir griddle.  Of course, that's due to the range dimensions, which the griddle has to conform to.
