I bought the set for my old MUM 8. Unfortunately, it turned out, does not fit. Mitlerweile it is indeed offered only for MUM X. Therefore, a point deduction. But since I still have the MUM 4, this shredder set is used actively with us. A small serving of cheese, onion, chop nuts. Coffee grind. Making salad dressing, spice mix grind. Powdered sugar and produce, and ..... Since I have small hands, it is the beginning was really hard for me to turn the attachment to the glass. Vaseline but quickly brought improvement and now after frequent use, it's easy. Easy to clean, it is also still. Blade guard on the blade and together with the glasses into the dishwasher. I have not regretted the purchase, although the price is without nich.
