(This review was collected as part of a promotion.) I was gifted a bowl for Christmas as I only had the metal bowl. I could never get the bowl to sit in place and it would move around so much so i had to hold it with both hands and only on the lowest speed. I received a replacement bowl after contacting kitchenaid.  Sad to say the same thing happened. It won't lock into place. For something that costs so much money I am really disappointed.
