Unfortunately, we are unable to arrange spare parts for this item from our supplier.

Yes, sure, the housing is made of black plastic, the rasp of dishwasher-safe metal. I am very satisfied with this item.

no. maybe. and the slices would probably also be too thin. besides, the device needs a break every few minutes, otherwise the motor burns out. and the shaft to insert the food is also relatively small, you would have to cut the quinces at least into quarters. and then the remaining effort is no longer big enough to justify the device anyway.
