KitchenAid Automatic Milk Frother attachment is the a great addition for my KitchenAid Semi Automatic Espresso Machine.It is easily attached  to the KitchenAid Semi-Automatic Espresso Machine.  You can not use this milk Frother attachment by itself. It  must be attached to the espresso machine to use. It is so easy to use and clean.I made hot chocolate with this milk frother and it tasted great.
