We bought the rotary grinder for the production of sprits. For this purpose, it is really very appropriate. The device is indeed entirely of plastic, but looks still quite robust. For meat but the unit is certainly not the best choice.
Two criticisms there trotzedem. Firstly, the crank was already in the supply fell apart (you could stick), on the other hand the device can be relatively difficult to clean. For pastry still ok in meat but not very hygienic.
