Although I was impressed with the KitchenAid Semi-Automatic Espresso Machine, this Automatic Milk Frother Attachment makes it even better.  It is light weight and sits next to and attaches to your espresso machine, or you can store it in a cabinet until you need it.  This milk frother prepares milk for your espresso to make lattes and cappuccinos.  Even though the espresso machine includes a steam wand for frothing, this attachment does a much better job. You can adjust just how much milk you want to make your drink perfectly.  The removable milk tank can be stored in the refrigerator.  This makes the espresso drinks that you prepare as good as going to a coffee shop.
