All the functions on this work great. It's a nice alternative to using a regular oven when you're cooking something small. I bake 6 muffins at a time and it's fine. It consistently toasts bread. It doesn't have a bagel toast option but you can use broil for that. The air fryer function works like a stand alone air fryer. The buttons and dials are easy to use. It would be nice if it had a light inside. Also be aware that it's very tall.
