I was honestly skeptical about the suction cup at first, but it sticks to my countertop like it's glued down. Even when grating a full block of cheddar

The suction on this grater is incredibly strong. I simply lock it in place and it stays put the entire time, even when I'm putting pressure on it.

What impressed me most was how secure the suction base is. Once attached to my granite countertop, it doesn't budge. I can grate large blocks of cheese, carrots, and potatoes without worrying about it slipping
