First, I have to agree, the hooks and brooms are too short because the dough is very fast in the holes and you have to scrape out all again .... or blender would almost sunk, so avoid high mixing bowls with a lot of content.
High performance does not have the equipment, much has gone on a little longer than with a better-quality mixer.
The cable is terrible, it's so bumpy and in loops that the cable always towards bowl goes to the mix (missing not much and I mix it with) so I have it wrapped several times around the hand wrap to prevent this (normally should a cable at least as "stiff" that this does not happen)
The beaters or hooks go for quite a while difficult to get out and clean. Today ichs then the mix often "crunch" hear something's gone quite right, she beat when mixing in firmer dough together, as if the device completely moved to the mix. I get out the broom now only when I press the top and bottom off draw: /
Not recommendable!
