In my view, super in order to chop onions, potatoes, cucumbers or equivalent. In more humid things like tomatoes, it is of limited use, because the sap can run out and / or it may matscht.
The blades are very sharp and easy to clean. If I do as potato dishes with Zwiegeln, I mince the onion first, then the potatoes, so the remains are pushed through with the hanging of the onion when cut remain.
What I like most is to clean the appliance immediately after use. Then we headed still fastest.
The device is used me as a substitute for a nearly identical model, which I had acquired in teleshopping years ago. Even with this I was very satisfied so far, only the blades were just dull with time.
I've then got another device and the old away. However, I quickly missed ds here, because it is so easy to handle and quickly usable.
For the price you do not go wrong in my opinion.
Disadvantage, or a question of taste:
The only downer is that with this, the distances are slightly larger than my old device or the blade just "fix" are. The pieces could be sometimes a little less. I have found here zumindst no choice with respect to the blade size. The would be nice.
