This replaced a 10 year old oven , things have moved on love the double oven , there are just the two of us now so the smaller top oven is perfect , I have my grandchildren once a week so the main oven is perfect , there are 2 shelves in the main and one in the top oven it also comes with a good sized tray and trivet that fits on the shelf holders without the need for a shelf good buy very pleased with it easy to use
