[hHre are several models and some ratings.](https://www.consumerreports.org/appliances/toasters-toaster-ovens/best-toaster-ovens-from-consumer-reports-tests-a2944358476/) it's a miniature countertop oven that can make toast or bake small meals. Some have convection fans as well. Great for making a meal for 1 or 2. Not as quick as a microwave, but better for real cooking.
