Works surprisingly well, I had not expected, since it is made entirely of plastic. The different sizes can minimize waste, but still lose much more Fruchfleisch and juice as if you rangeht with the knife. There is really fast, cuts very well, and you have pretty equal slices (spiral). I would not buy me one more time, I'm switched back on's kitchen knife, precisely because of the waste, but to whom the speed is more important, is well advised with this device. Cleaning easily in the dishwasher.
