I'm having problems with his right wrist and sought help when cutting z. B. from hard vegetables. That's why I chose a device with relatively powerful motor (here 180 W) and not too heavy weight (here almost 700 g). Cream pie and like I can cut even without aid with a good knife. My test object was a celery-tuber. The electric knife "managed" the tuber. However, it took longer than I expected and I had to treat the unit after three minutes a break. In the long run, the weight of the knife is made uncomfortable in my wrist and felt I could smell the engine, but only weakly. The volume I felt to be appropriate. The unit is specifically suited for cutting of frozen NOT.
