Reason: from the 1st to the last operation (and it was often used) smelled strongly of burnt oil every time. And the away not only for sensitive noses just above the device but still loose 2 meters.
Added to this was that smaller chunks at the bottom of the pitcher accumulated and were probably not transported with upwards (Banana Shake) and so until the very end - were not crushed - despite persistent mixing.
But the smell was the worst and is not in the long run
