Despite having been in the coldest part of the freezer on the coldest setting for weeks, this will not freeze even chilled mixture beyond "milkshake" consistency.  It worked for about a year but after that the problems began.  I had a Cuisinart stand-alone that lasted more than 8 years and when that wore out I switched to Kitchenaid because all of my other appliances have been great.  This is a tremendous disappointment.
