I too like others is replacing an older one.   Yes it is larger than the older one but is is surely cooking much faster then the instructions on a recipe due to the convection portion.   I just wish the Toaster portion would turn off when I open the door as the last one did and I didn't have to keep turning the knob to make it start.  With the old one I was able to keep the Toast Button at one level and you just pushed the button to toast and it would stop when you opened the door.     Now if I feel it is toasted enough I have to make it go through the rest of the cycle as I don't want to force the knob back to stop.
