Smoothly operating system.  The oven feels as if it is simply awaiting my orders for it to begin executing them.  For example, pre-heating when called for as in baking and not when unneeded as for broiling. The roller rack facilitates handling of hot bakeware and the ability of the racks to handle the high-temperature cleaning cycle enables us to forego the miserable exercise of manually cleaning them.  Overall, I anticipate we will be pleased.
