Once again KitchenAid has impressed me! This automatic milk frother attachment is easy to assemble and use thanks to the helpful manual it comes with. Each step is written out easy to understand and the pictures that accompany each step help guide and make sure your assembling it correctly. Once attached to the espresso machine with a turn of a knob you can add the perfect amount of milk/foam all in one spot. I even experimented with my husbands coffee creamer and worked out great! Overall a great product to help bring your favorite drinks home!
