I received this item as a gift from my daughter and was so excited! That is until I went to assemble it and found that it was not compatible with my Professional 6000 HD mixer. The drive assembly will not fit onto the head of the mixer because the head of my mixer is more of a square shape and not round like the assembly and other models of mixers. I then looked to see what models the ice cream maker was compatible with and the only thing I could find is that it is not compatible with the mini stand mixer, no mention of any other models. Again, I'm very disappointed because I've come to think of KitchenAid as a high quality brand and have never had a problem with any other attachments, but this time they disappoint.
