This works GREAT, I just can’t handle coffee anymore so I never use it for lattes now. Black Veken milk frother and heater (just take the end of the frother off, the spring looking part, and it will just heat your milk, that’s what I’ve always done but I guess you could just press either the “heat” or “froth” button :) directions should be super easy to find online if you’re really unsure what to do haha
