It's nice to have the automatic milk frother on hand for times when you may be entertaining guests and might be making multiple servings of drinks at a time due to the semi large reservoir. However in my opinion the frothing capabilities are mediocre at best. I wouldn't spend extra money on this as an add on component to the KitchenAid semi espresso machine if not already included as a set. A lot of other comparable options already available on the market.
