Overall, the unit fulfills its function and I've already made the kilo fries with it. Unfortunately, the potatoes become jammed due to the oblique feed often so that it becomes almost impossible, these continue to push through the knife grids. Then you have to press them out awkward again in the opposite direction. Or you try to spend correspondingly more power. Which reminds me but the plastic body is then also unfortunately canceled. Even the knife grid for the smaller chips has so warped that have later released single knife and it is no longer usable. For the price the device is to use well. Who wants something permanent and stable, but should rather invest a few bucks for another device.
