This is actually a replacement for a previous Advantium I had for about 13 years. (The previous model was damaged when my home was struck by lightening.) This model had different dimensions, so my cabinet had to be modified, but have to say I like this one a lot more than the previous one. This one can fit a larger casserole dish and I love the second rack. As a busy family, I love the option to cook much faster than a regular oven. The preprogrammed speed cook options are a blessing for my 12 yr old son. I also love the convection option, that my first Advantium did not have.
