This unit has 4 different size burners from simmer, regular, high, and ultra. The largest burner, ultra is at the front right, while regular and high are on the left. To me, the locations are the reverse of what I use daily probably because I am right handed.  Inconvenient.
Also this unit has a large oval shaped burner in the center, perfect for a grill or griddle.  However, it does not come with a grill/griddle. Yet a very similar model with a central Round burner comes with a grill/griddle. I think someone in marketing is confused as to what accessorizes belong with which unit.
Finally, the upper oven is not uniform in heating. It's hotter towards the back.  Cupcakes came out brown on top at the back of the oven and tan on top at the front. Same with a chicken breast. A little burnt for the portion at the back.
My main gripe is no grill/griddle included, and I did not analyze the burner location vs how I mainly cook.
