I replaced my old, rusted metal grater with the OXO Seal & Store Rotary Grater and am very happy that I made this decision. I absolutely love how safe this product is and how I have not cut my hands once since using it. I used to cut my hands all the time when I used my old metal grater. I did not think that the OXO Seal & Store Rotary Grater would work as well as a metal grater which is why I hesitated switching products for as long as I did. The end result is a grater that works equally as well (if not better than) the metal grater and hands that do not get cut when I grate fresh parmesan cheese for pasta dishes. The block of cheese fits securely into the OXO Seal & Store Rotary Grater and the lever firmly holds it in place. The grating handle turns smoothly and the cheese is grated nicely and evenly. I am impressed with how easy the OXO Seal & Store Rotary Grater is to clean and am very pleased that it is dishwasher safe. I am very happy with this purchase and anticipate it will last for a number of years.
