The EO420 toaster oven features a 4 slice total toast capacity with a unique toast color selector allowing the user to toast bread based on color preferences; this provides a much easier selection of toast cooking temperatures than listed numbers because it gives an overall better projection of how the toast will turn out.
The DeLonghi EO420 toaster oven includes multiple cooking modes along with the usual bake; additional modes include broil, toast, and keep warm. The EO420 device allows users to always know the operating temperature or cooking temperature thanks to a visible temperature quick check gauge. The device itself comes bundled with a bake pan and separate broil tray. DeLonghi additionally claims the EO1200.1B toaster oven is "easy to clean" thanks to a removable crumb tray and non-stick manufactured interior.
The DeLonghi EO420 model is nearly identical to DeLonghi's lower end EO1200.1B toaster oven with the exception of a black exterior finish on the lower model as opposed to stainless steel. Users simply looking for an equally capable toaster oven that don't mind the black exterior can purchase the DeLonghi EO1200.1B for a much cheaper price. It should be noted that the EO1200.1B model features a larger 6 slice interior capacity than the 4 slice capacity of the EO420 model.
