The typical comment about toaster ovens is that they’re bad at making toast and they’re bad at being an oven. Just learn to use the oven that’s already installed in the kitchen.
My toaster oven uses way less electricity and doesn't heat up my house like my big oven though. When I make cookies they are done in 12 minutes to perfection and it plugs into a normal 120v outlet. I doubt my big 240v oven with the thick cables for lots of amps is even preheated by then.
I lived several years in a tiny apartment without an oven in the kitchen. I learnt to make just about everything (up to and including a soufflé) in a toaster oven after a while.
