I have this mixer for 14 days, almost every day, in use. After I read many product reviews on different devices, I have gained from this unit Klarstein, for the following reasons. He has 1000 watts (instead of 800) and is to mix in a position green smoothies. He has a glass container (and not plastic), and it has an acceptable volume. He also has a achtflügliges knife. (Instead of six wings). Overall, I can, after 14days use only positive things. One really gets creamy smoothies, within the shortest possible time, also green smoothies. He shreds frozen berries and ice. You can use the corresponding button, and mix when needed again using the manual function, or Pulse button on. It is easy to clean. Only, you need to practice a little until you get the hang of for removing the glass jug. In the first three uses he has smelled something after prolonged use, but only slightly. I also very respected it, because this lack has been reported in other devices frequently and be very distressing. So far I am very happy with my purchase !!
