I think I received a faulty product. I assembled the automatic milk frother per instructions, clicked it into the espresso machine. I updated the attachment settings to froth milk for a latte. After LOTS of finagling with the espresso machine buttons, I FINALLY got the machine to select the milk frother setting. It would not let me select 1 or 2 (indicating how much milk) so I went ahead and pressed Start. The machine made lots of noises but the attachment did nothing. The milk stayed cold. I double-checked my assembly/connections and tried again, after lots of finagling the buttons since they are NOT USER FRIENDLY. Still nothing. So I tried the manual function with the wand connected to the machine and tried frothing/steaming milk in the metal container. At first this seemed to work, but then the final steam blew milk EVERYWHERE and ruined the nice foam it had going. So no, this product does not work as intended, it is useless.
