At first, I thought I would send it back because there were a couple of hiccups. I called the customer service line and was given some great advice! Now I use the oven all the time. I don't know how I cooked without out. The thing I like best (and didn't believe was possible) is that I don't have to preheat when using the convection features. I just wish that the top of the oven was made with the same material as the sides so it was easier to clean.
