The consistently positive reviews I can not understand. I have purchased the product in a WMF business. When unpacking I noticed unpleasant that the plastic frame is not the bottom of the glass jug removable. It is bolted to the pitcher. If there is something running in between - how can you clean that? Three times I can use the mixer with no problems. At the 4th time the disaster: I have the knife assembly including the respective seal as every time the pitcher well tightened - exactly as described in the instructions, counterclockwise and beautifully appointed. It was clear from the experience with built according to the same principle devices, this connection having to be a weak point! That's why I like every time an extra check whether everything is really sufficiently strong top and tight and have first times only filled water - nothing came out below, connection was tight! Water back out and first introduced the thin liquid components of Mixgutes, and to check whether it remains tight - everything seemed ok! Then 1 chopped orange and 1 lemon crushed to the shells of such organic fruit I had specially cut into very small pieces in order to minimize the burden on the mixer. Thus were about half and half fruit particles Kefirmilch in blender jug. Then turned and the speed slowly increased to maximum. After just 20 seconds mixing (of which perhaps five seconds maximum) sudden shutdown of the mixer! When I wanted to I check what's going on and the pitcher took off, the mess: the knife assembly had come loose and the now-liquid is Mixte Mixgut distributed on countertop and floor. The knife assembly is operated counterclockwise when mixing, so it should be by the operation alone can not solve (if the engine is in the correct direction drives). I've looked at the two plastic screw on the blade assembly and the plastic version of the jar again accurate - that do not make trustworthy and stable impression: total appears the thread is not to be deep enough, the thread flanks are too short and turn right 2 time into the thread and the thread flanks in my opinion should be flachwinklig. Apparently the thread of the knife assembly / plastic version Krug is designed so that the connection does not stop at maximum speed / load safely stable and replaced by the vibrations of high engine speeds, the blade assembly from the pitcher or the pitcher can be pushed off the knife assembly. I'll bring the device back and insist on conversion (money back), the risk of repeated such disaster I do not go in.
