I received this as a Christmas present. I have a Cuisinart food processor but wanted this one because you are not limited to the bowl size allowing you to keep processing without emptying each time the processor bowl was full. It assembled fine and my first task was to grate several blocks of cheddar cheese. The first two blocks went through ok with very little pressure needed to advance it down the feed tube but the next block post grate blade got packed into the drop shute causing all the cheese to backup. I had to disassemble and clean the entire thing before completing the task. I have not tried it yet on anything else. So just a warning when grating cheese keep an eye on it.
