This is a standard-size box grater. It's sharp and has a comfortable handle. Shipping was fast, and I received exactly what I expected. The price is good also.
I have grated Monterey Jack (large holes and slicer), Gruyere (large holes), and Parmesan (medium holes). The grater did a good job on all the cheeses. It made quick work on 8oz blocks of the Jack and the Gruyere. I was especially impressed with the fast grating speed on the older, drier parm as this takes forever on my microplane graters. For reference I'm a small person w/o a lot of arm strength.
If you wash off the grater soon after using it, it's easy enough to clean by hand. I'm guessing that cleaning by hand will help it stay sharp longer.
It is a little futzy to get the bumper on the bottom of the grater on, but I'd keep it off for washing to make sure the bottom dries out faster (preventing possible rust). The bumper is useful if you grating into a glass dish or slippery hard plastic; I don't use it on a less slippery surface like a a wood board.
