The container is non-slip, and the rest holder can be easily and securely fastened, so I think the use of rubbing total for sure, although I mainly the sharp knife of the slicer instills proper respect.
I particularly like the uncomplicated cleaning the grater in the dishwasher.
The attachment for slicing has pretty excited us: without much effort can be sweet potatoes, carrots and cucumber cut into equal slices. The slice thickness is not variable, but I did not find bad, since the thickness is just right for us. Even a slightly thicker piece is due to the distance of the rest holder left in the end, but not overly bother us. For the slicer we would give the grater 5 Stars.
Unfortunately, we can not start as much with the other two towers. Both cause quite a mess in the kitchen, because the vegetables flying in all directions. Too bad, because we would like the grater, used for grating not only for cutting.
My conclusion:
Great slicer, rather worse Raspler.

Unfortunately the rest holder has third Dishwasher transition will not survive unscathed, because (although the first two rinses were problems), he is now full of dishwater. For days he is on the side and is between shaken repeatedly, but the water is still not completely run out. So that the whole product is unfortunately quite useless, because I want the rest holder no longer use for cutting vegetables, if there is a risk that a few days old dishwater enters the food. Since I found the initial grater very good, I am very disappointed and unfortunately has yet to pull off a star from the former 4 stars because the product has become extremely unhygienic and thus unusable. Pity!
