Take expresso to a new level and impress everyone with the frother attachment. Easy assembly and not too difficult to add or remove from the expresso maker. I like that the tank on this is easy to clean and the steam wand is easy to take off for cleaning. I can either fill the tank with cold milk or put the tub directly into a milk container. The tank holds about 17ozs of milk, which is plenty for a few cups of expresso. We sometimes like to just do hot milk for cocoa so it’s nice to have the option of putting the tube into a larger container. Easily adjust milk amount and texture with the aeration knob with some practice. This is a great optional feature for our expresso maker that helps us get professional results at home.
