I was very excited about this since I always have milk with my espresso but I found this addition to my espresso machine nice but I had higher expectations than received for it. It works great for a shot of milk if you are doing a half and half but not so much for a larger latte. Also, the milk was just not as hot enough temperature for my taste. The function on the espresso machine itself seemed to make my milk at a hotter temperature as well as had more of a froth.
