A real luxury segment. While I make the coffee, I turn on the thing. About 2 minutes later I then 1 liter tiptop milk froth for my bar. Enough for two robbers glasses for my Hasi and me. Drawback is a little cleaning (the body must not immerse in water), so also the term luxury. In my opinion not usable as bit of a hassle to clean for daily use but a real luxury on the weekend when I get up and need only press the button. Recommendation: Do not let the appliance run until the end but on the verge off or remove it from the base otherwise the milk will be liquid again. This part has repeatedly saved my weekend. But four stars because of the cleaning history.
