After a big disappointment in the first three uses due to a bakelite burnt plastic smell in the soup making it inedible. I found the solution to remove the unbearable discomfort, I soaked all supporting the mixer knife in hot water and bleach in hot white vinegar too, after several rinses, the next soup n longer had any bad taste.
No monitoring, a single container washing to his soup, this device has a place in any kitchen or soup sits down to eat every day ...
I do not regret my purchase, except that it is a bit noisy when started mixing.
