I cannot describe how glad we are to have the KitchenAid - KitchenAid Automatic Milk Frother Attachment. It was very easy to attach to the Espresso machine. It did take a minute to figure out how to take it off though. It is so easy to heat and froth the milk for our drinks, and now we can do it on a larger scale. It is so much easier that the hand tool. The attachment is also easy to clean. We love it and you will too. I recommend you add this to your KitchenAid Espresso Machine!
