"GARBAGE"
This thing sucks.

Basically the mechanics/ergonomics are designed horribly and so you can not get enough leverage or compressive forces on the harder cheeses to grate them.

You basically have to squeeze very hard on a really uncomfortable handle which really fatigues your hand, and I'm a big strong guy. No one in my family uses this thing.

For softer cheeses like cheddar it's equally miserable. It's still uncomfortable to use and on top of that, the cheese gets all caught up in the drum turning it into mush.

This thing is going in the garbage today.

"Try a different grater"
This grater really does not work as advertised. Harder cheeses take forever to grind and soft ones get stuck in the grating tube. Try a different grater - this one ain't work the 20 bucks.

"Bits of metal is not what I want with my cheese"
At first I was pretty happy with the grater, but after a few days of use I started to notice that I was getting small shavings of metal as well as shredded cheese. I am no longer using it and would not recomend it to anyone.

"It is functional..."
Well, I'm not terribly impressed with this metal rotary grater. Yes, it will grate cheese, but the gap between the drum and compartment that holds the cheese is a little over 1/4 of an inch. This allows for the cheese to get 'gummed' up and eventually that large wad just falls through. Also, for harder cheeses this means you're constanty picking out chunks of cheese that should have been grated.

I've yet to find a rotary grater I'm happy with. I've broken several plastic models within 2 days of owning them. While I've yet to break this metal model, it just doesn't perfrom very well. I'm still using my stand-up grater.

"Save your money"
I bought this to replace my old Mouli grater which finally bit the dust. Big mistake. It is sturdy and reasonably well designed, but the grating surfaces barely work at all, or at least mine didn't. To get it to grate cheese takes a long time and a lot of muscle, so much so that you are likely to start wondering how badly you really want the grated cheese. I tried the grater drum on reasonably fresh Parmesan and later tried the shredder drum on Jarlsberg. Neither drum worked satisfactorily. That may be because it is made in China where hard western-style cheese is nearly unknown. Yeah I know it says MIU France but the box clearly says "Made in China". I finally got so mad I threw it out in frustration.
