KitchenAid Countertop 12"Oven-Black

Bought this a month summer to keep house cooler by using instead of oven for smaller jobs. Outside of unit gets very hot. Takes forever to reach desired temp. Not for toasting. Instructions say to preheat before toasting. Huh? My 4 slice toaster beats oven 2 cycles to 1, preheated and 4 to 1 NOT preheated.
