I felt like leaving a review to this convenient machine, as perhaps some reviews are not entirely fair.On taking it out of the box, it seemed so simple, almost simplistic, I was afraid back it would go. I was expecting some "feeding mouth" or something, but on using it (parmigiano so far, but I'll update if I have problems with other functions) I was delighted though, even if you have to kind of hold the piece of cheese yourself. You have to be a little careful when approaching the end of the piece of parmigiano but it is really not that difficult. The grater is sharp enough. I understand why the cones are not THAT sharp. They are sharp enough to do the job well, but not at a dangerous level, like the sharp blades of a food processor (which of course have their own advantages, in other uses).The grating process is VERY easy and quick and while one doesn't get a huge variety of sizes of the grated product, the one that is offered [the other four cones are more for different kinds of slicing] is satisfactory for most culinary usages. Tip for those who complained about the cone falling: don't just push the cone IN, twist it a little. It will hold on fine.To be honest, I'd have liked it even if only for the grating . . . if the other cones work as well, I'll consider it a bonus. It helped I "caught" a better price than the usual one... a little under 90. Shop around.If, like me, you are sick and tired of pushing parmigiano through a hand-held small grater, or getting a mess in the food processor for a measly cup of grated cheese, you'll enjoy this. Metal, it also seems it will last forever.
