Benefits:
silencer (with respect to the electric)
Economic (no electricity)
easy to use (I was afraid to have a little too forced to grate, but no problem, it goes alone)
Many rapes
perfect fixation suction cup (does not move)
Disadvantages:
not dishwasher safe
the foot is a little small (put a small bowl to retrieve the grated foods, because the height under the appliance is low)
design problem (or just the product received): it seems to lack a cache between the gear drive and rape, this is annoying because of food scraps can go jam or stick to grease the gear
