Do use a thermometer to test the temperature before using! The first time I used it, it got so hot that I checked it with my oven thermometer and it was 50 degrees hotter than what it was set at! I love the ovens size, with its extra shelves and pan. The  outside surfaces get hot, but cool down quickly when turned off. Wish the electric cord was a little longer. Otherwise, it’s a keeper and has been very handy.
