“I thought that this might not be fine enough for making citrus zest, but I was wrong. It works really well and does not take long to grate the rind off a bunch of oranges/lemons. I also use it for grating fresh ginger (to put in my ginger biscuits).
My old grater annoyed me - a lot of the food ended up getting stuck in the grater and I risked cutting myself digging it out. No matter what you grate with this, it can be easily wiped off the grater, so no wastage. And it cleans up very easily - either in the sink or dishwasher.
P.S. I bought the coarse grater as well, mainly because it is so much easier to clean than my old one. It is also easy to grate directly into a bowl.”
