Let me get something out of the way first-THIS IS SMALL. 4 slices of bread *may* fit, but the bread slices will be touching each other and for some brands of bread-4 slices won't fit. 2 chicken breasts will be a tight fit. If you take out the bread tray, you can fit a small bowl in to heat, max 8 inches wide, 7 inches wide and 5 inches tall.
Very easy to use-3 dials- one for heat level, one for time and the 3rd is well, not needed (middle one). A stop watch chime sound comes when it works and a small red light glows when it is ON. Heat builds up fast, 2 slices of bread toasts to a crisp in under 2 minutes flat.
Body of the toaster gets warmish hot after 5+ minutes of usage. During initial use, a burning smell comes, this is normal apparently. Doesn't feel cheaply built, but built to a cost it is.
If you need a small toaster oven that is simple to use, average built, cheap to buy, and easy on electricity consumption, would recommend this one.
