I've had my Bosch Universal since about 1989. I bought it along with the blender and large slicer shredder. I threw away the metal chuck a few years ago. I called your store and ordered a new one which arrived within a couple of days. I really can't be without the slicer/shredder. Nothing matches it for shredding cheeses, carrots, slicing potatoes and cucumbers. - Rose Breitkreutz - 2019-04-02
