Device does what it should, it is hot! Toast is not super-uniformly brown but that I have not seen in any toaster. So overall good value for money. Bun Warmer is quite stable. Stay with us almost always on the toaster and does not interfere. Metal surface is generally quite hot. Can one expect halt with. Prior to the first toasting we leave the unit 2x run at the highest level (outdoor). After that was actually no disturbing odors of any vapors determine more.
