Review (5/5): Don't understand how it works. And don't care. It does.
OK I don't understand why this makes much nicer warm milk compared to using a standard mug or glass. I suspect it's the angled bottom. But who cares? This pitcher, combined with any motorised milk frother makes milk, soy milk or almond milk that is silkier. It's not quite the same as steamed milk, but very very close.
Excellent companion with Handpresso Wild for making flat whites or lattes and the like.
