The only thing that confused me was the previous reviewer. And as the following:
So, yes, it is true if you have (fixed) new potatoes, the last potato is not necessarily by 100%.
BUT: You put simply a next potato and this pushes the rest of the Vorkartoffel anyway through. Logical, right? Thus one has the potential "problem" at best during the last potato that this does not go all the way through. But even that is not a drama: With gentle thumb pressure to the punch surface and already she's through.
With a little thinking along the previously described problem is thus none at all. - I was not thought through this review a little annoyed, because it has almost stopped me to buy this product. In fact, I find price / performance stunning. Had 2 plastic utensils which are both just broken too soon. Absolutely This metal device no problem, and even after many fries servings (we use for frying the Actifry, do not worry, we still have normal clothing size ;-)) it still looks like new and can each potato with little effort to be French.

By the way: Even today - 06.04.2015 - untroubled in use. Absolutely robust part, still like new. Prima!
