This automatic milk frother attachment works so well with our KitchenAid espresso machine. It is very easy to setup. Then, pour in milk, adjust the settings according to your preferences, and press start. That’s it! We consistently get great results every time. The milk reservoir can also be removed and refrigerated for later use if needed. The front of the attachment also has a handy storage compartment for espresso machine accessories. It’s also fast and easy to clean up!
