Spacious and excellent value, but keep away from kids because top and sides reach 170 degrees F when oven is at 450—there is no insulation.  Exterior and inside dimensions are as specified but drip pan and rack make the maximum usable interior height 5.5 inches.  Icons on keys; helps at first to make enlarged copy of small picture in manual and write notes on that.  Nice to use and straightforward after you use it once or twice.  We use as oven, not toaster.  Would buy it again.
