I was after a long search and weigh for this device chosen although it probably is "only" about 23,000 revolutions create and "only" 4 blades instead of six have to. For this it has decent wattage, the only addressable optical ugly among all these professional mixers and a big Glasbehaelter instead these plastic parts. So far I have had no leaks other the problems mentioned herein. This part is great, whether apple, zucchini or salad ... the get everything small. Chopped ice cubes with pure are not to taste, so small they are. The Device is of course noisy but you would expect from a mixer with the power? Very valuable in the design and appearance, yet completely thrilled as well priced really an alternative to the professional parts!
