I loved my ice cream maker attachment for years...until I upgraded to a 7 quart pro-line (still household!) mixer and just went to mix up a batch of vanilla ice cream for a party and discovered the attachment does not fit over the mixing post portion of the machine. Great--now I'm off to a cookout sans the ice cream I was begged to make by the host. Thanks for lying, KitchenAid. This attachment fit my 6 quart pro-line mixer perfectly fine. Completely false advertisement since it boasts being "approved for use with all KitchenAid household stand mixers". I'm livid.
