I bought this toaster/oven a few weeks ago. So far so good. I have one observation and one concern:
1. It toasts slowly, and seems unable to give a really dark result. One may need to add more toasting time after the bell for additional color.
2. It smells. I'd seen other owners comment on the odor burn in time... Ours continues to emit considerable odor if it gets well-heated (smells like wire insulation getting cooked). To assuage my own curiosity, I got bold and opened the unit. The attached photo shows the insulation used on top -- with some of it turning darkened. It also wreaks of the very hot insulation smell. 
The insulation appears not to be FiberGlass -- but some synthetic fiber. I'm going to look into replacing that with true FiberGlass (after I check for the thermal tolerance of the substitute material).
