It is a very versatile little machine.  It is a great alternative to heating the large oven when you just need to cook something small. This unit surprised me at how fast it works.  I've used it, rather than the microwave, it's great for for reheating small dishes and leftovers!  Not only does this use less energy than heating up the large oven, but it doesn't add as much heat to your kitchen as using a larger oven.   It's a compact size so it doesn't take much space on countertops so it fits everywhere I place it. It is also super easy to clean up if you keep up with it with a removable crumbs tray.  This convection oven is simple to operate. This one heats quickly, the settings are easy to use, and many choices. A little quiet click reminds you that it's cooking, and a nice loud bing says it's done and turned off. It came with nicely printed clear instructions.
