I am a little disappointed by this unit. On the one hand, of course, pleased about a lot of foam, but here as much foam is produced that it has no more liquid. So if I can I made re a cappuccino not only to foam, but only have to heat the milk, then pour the coffee again. Unfortunately you have to wait three minutes before the device re-used (totally annoying when you visit) .... after 3 minutes (but I think this is a not always, be honest) I foams the rest of the warm milk then , The fact that you have to change it to use, you have to "dig" with his fingers in the milk until it is replaced :-( I would not buy this frother again, rather then spend more money and have a bit more comfort.
