I love the whisk for my Bosch MUM5. When I bought the machine I was beastly annoyed because with the supplied whisk the dough, especially for butter, on the walls of the bowl crept and stuck there and was no longer processed. The rescue was carried out in the form of this beater and I bake again gladly. Without him, I would have sold my food processor. The dough is only slightly hanging on the walls, hence the 1 star deduction.
