But: On several occasions I had to reorder knife because they crush the ice or hard cheese chop now and then get stuck and then bend the gasket it is necessary to replace every now and then. However Unold, with sensational service for spare parts, can only be recommended, call away .. So the order is not really a risk, the price is absolutely fine - for the same money you get otherwise only plastic devices with much less power.
I now have the unit re-ordered because it is in operation daily and knife and seal were again due and the warranty had expired, but this time I got on a Monday device: From the first placing a plastic part has solved on the base. But this time, the return to work easily, going right back to order me a new one.
Make the knife a little more stable and offer a ram with, so you can follow up on fruit (I use a random matching pestle from an old device, so that the mixing and pureeing doing much better): My desire to Unold.
