..wollte actually have only a bread slicer, which I must not worry about cutting force in hard bread. the wave washer is great, so far no complaint. Now my wife uses, this cut also to cheese, with the same shaft washer, Thins, am fascinated and shopping is also cheaper with larger packaged cheeses. So now the disadvantages: the holder is made of plastic, I like to unpack on the ground, because that was "hidden" in a box and I did not immediately seen and lifted the machine and plumps it was on the ground and broken - the Plastic is now broken and no longer useful. Advantage, they do not necessarily need to cut bread - the spare parts price unpackbar expensive: =) ..sollte aluminum and or sein..hoffe this helped ...
