I bought this as a replacement for another 6 years old, and it was not my surprise (disappointment rather) than to see that for double the purchase price at the time, model is twice as big and ten times louder than the old ... It's not complicated, it's almost as much noise as the floor vacuum cleaner, so much so that not more talk when it is running. It's still a huge negative because if the meal ends late (or early during breakfast), it is impossible to use it or wake everyone ... Yet it seemed to have read in the comments that he was silent, then either I was wrong model or mine is faulty. Otherwise it sucks well, despite its "mouth" much narrower than my old (thus forced to make more passages). In short, if it again, I do not would resume this model, and I do not recommend it.
