We have to do with this unit repeatedly tried Maroni and we are really just disappointed. The Maroni last much longer than in the oven, they taste no better, they can be opened and it takes a lot worse lengths. With 25 minutes, the chestnuts are never through. The Maroni scent in the house described here, I can not smell, I smell nothing, just like chestnuts in the oven. An absolute bad buy, too bad.
