We came across the advantium when we were looking for a built in microwave for our remodeled kitchen.  It seemed to good to be true but after checking reviews we decided to go for it.   Yes it is a bit pricey but the convenience and energy we save from not using the conventional oven makes up for it.  Now we grab a pizza from the freezer and within 9 minutes have a crispy crust and gooey cheese meal.  We also can grab frozen chicken nuggets and have crispy and ready to eat within 6 minutes.  This oven has become our go to for just about everything over the past three years.
