Perfect size for a 2-person family. I haven't used my regular full size oven since I purchased the toaster-AirFryer- Oven. It's very quiet when air-frying. I haven't tried the dehydrater or proof. It cooks fast. We LOVE IT!! Please watch videos on cooking with this. Its very helpful in deciding to purchase. Directions are pretty easy. Recipes are awsome especially Candied Bacon and Chicken Nuggets YUMMY!!! I would buy this product again!!!!!
