I have only had limited use and perhaps the choice of cheese was too soft (Colby) but there was a lot of waste on the grating (fine) setting. Grating carrots was also disappointing. Again a lot of waste. I tried slicing spring onions as the demo video shows that happening with great results. But it all ended up a mush.
I found the instructions very confusing and the indicators on the actual blade are not clear. Trying to work out which way to put the disc wasn't clear. I bought this thinking it would make slicing and grating a breeze with professional results, but either I am doing something wrong or the product isn't as good as described and demonstrated.
