Product review (2 stars): No different than the regular size in heating area.
I am in love with my regular induction burner, which happens to be the inexpensive MaxBurton (which is recommended by Cooks Illustrated).  But, because it has only a small heating area, about 5 or 6 inches in diameter, I ordered this induction burner because I thought it would have a larger heating area, signified by the larger circle on the top.  I tested both of them using a large frying pan with a cup of water in the pan.  Both of them caused the water in a small circle to boil but did nothing to the significant peripheral area.

Perhaps the XL is supposed to refer to the entire size of the cabinet that holds the heating area.  I don't have any pots that won't fit on my regular induction burner.  But I have plenty of them that are larger than a 6-inch diameter which I would like to be heated by something as big as the pot.

I also found the single-knob control to be less than helpful.  The much cheaper Max Burton allows one to choose the power, or the temperature to hold the pan at, and also provides a timer so that one can go off and leave something to cook at 250 for 3 hrs and have it turn off by itself.

Therefore, I am returning this, and am still searching for an induction burner with a larger heating area.
