This great innovative little machine attaches to my espresso machine. It prepares the  milk for my excellent lattes and steams the milk to the perfect temperature and superior flavor via the automatic temperature control. This is a perfect addition to my espresso machine and offers way more than I expected like programmable foam adjuster for amount and texture. This awesome machine even comes with a cleaning brush. No more coffee shops for me since I can make lattes at home as good if not better.
