So far the oven works well. 
The design of the raised surface burners is a safety hazard. Pots and pans can tip if  not  put squarely over the burner. 
The raised burners also increase the time it takes to boil water. It They are not energy efficient as more gas is used than by other range models. With my prior range I could heat water in my electric kettle for tea and heat a can of soup in the same amount of time. It now takes twice as long to heat the soup on this style of burner. 
We purchased this model to fit into a small kitchen, but the raised divided burner grills waste counter space as items can slip off the edges especially hot baking sheets. 
The range has feet that are a little over 1 inch high. Just high enough that dirt and crumbs can accumulate under the stove but not high enough for a dust mop to enter. It is not handy or possible to move the heavy stove as it would disconnect the gas supply. Therefore it is impossible to keep the kitchen clean.
