The device does what it should. Personally, I can no real disadvantage compared to other manufacturers like stirrers notice, but the costs sometimes much more. Everything seems so far as processed solid and stable. Nothing wobbles, nothing seems "cheap". With the included accessories also all meaningful for me possibilities are covered. One complaint I have, however: The Aufsetzmixer has quickly left the service. The knife has simply no longer rotated. Here it might be better if the connecting parts were made of a different material. I have received from the manufacturer at the time free replacement, but the unit was there also fairly new. Here one or two stand-alone mixer is likely to be well-resistant. So you should not insert too solid food items in large quantities and possibly proceed more cautiously. However, this criticism refers in fact only to the additional top mountable mixer. The stirring unit itself acts like this, so you might as soon not harm it and I'm still very happy with it.
