We got this oven because when our microwave failed we couldn't find a compatible matching microwave for our old oven, so we we replaced both units with a matching pair.  The Advantium is a microwave, but so much more.  It is larger than the typical microwave. It is also both a convection oven and a radiant heat oven with the ability to combine multiple cooking modes to provide rapid cooking not available with any single method alone.

So whether you need an additional standard oven a microwave, or speed cooker, this unit provides them all;
