Query: Returned it for a refund

I'm a big Black & Decker fan so I thought this grater would be perfect--on the commercials it made grating look so easy. Well, not so. Since the grater itself is held in one hand with your thumb constantly pressing on a slider to activate the motor and the item to be grated is held in the other hand, trying to keep the food item steadily against the moving grater became a major upper body workout and bits of food went flying all over the place. Trying to grate anything harder than mozzerella cheese made the blades come loose from the housing (the lid holding the blades in place didn't secure well enough and easily popped open) which became extremely dangerous. We weren't able to grate any food that we normally use without pulling out the old hand grater or Cuisinart so this grater very quickly became a useless machine taking up precious storage space--so we returned it for a refund.
