My mother just had one put in a new house. She loves it, swears she'd never go back to a regular oven again.
All though when they installed it they had the wrong gas jet in it, it was set up for natural gas instead of propane. First night I put a frozen pizza in it, turned it on, heard this...... VROOOOOOOOOOOOOMMMMMMMMPPPPPPPPPPPPPP!!!!!!!!!
I thought a jet was taking off from the front yard. Pizza was crispy in 30 seconds flat.
I have one and it's not worth the money. You can cook a lot faster but the food (except potatoes) tastes like you cooked it too fast. It has become an expenmsive microwave in my house.
