This will be our third Advantium.. We have had two Advantium over the range microwaves. They never gave us problems. We moved, thus we had to purchased a second Advantium microwave. Now, we are remodeling our kitchen, purchased the Advantium  built in wall oven so that I may be able to reach it.  Also, we utilize the speed cook for warming up left overs. It saves on food that we would have normally thrown away Although the price point is higher, it is well worth it to us. We could have pick a lower price point built in, but we love the Advantium, hands down.
