Terrible machine, avoid at all costs. Auger and housing are made of aluminium and no matter how much you wash or oil them, black aluminum particles keep coming off them onto the food. It runs like a tractor too. There were loose flakes of aluminum on the inside of the auger housing that easily broke off if touched. I'll be binning this machine. I got a refund after all my complaints. So I'm not out of pocket. Stick to a machine that is all stainless steel.
