Query: I Didn't Warm Up to This Oven

Two main problems with this oven.1. It heats slow and takes forever to toast. Previous oven would toast 2 slices in about 4 minutes. I can make an omlette, cook it and eat a portion of it, before this one finishes toasting. Start toast, take nap, make omlette. That has become my routine.2. The convection does not work the way it should. My pizza came out more evenly cooked in my regular old Black & Decker.It's undepowered for it's size. It also tends to rattle due to the convection fan unless you set the door just the right way.Don't buy it. If you want soemthing cheap, stick to Black & Decker.
