First of all, if you want fast, get a traditional milk steamer. This thing takes 5 minutes. However, if you're willing to wait, this thing magically transforms milk into a perfectly heated form, with zero skin and a lovely froth. I use it to make masala chai and hot chocolate, and it's magic. It's so easy to use and clean, you'll love that with the press of a single button, and five minutes of patience, you've got perfectly heated milk. I sound like a shill, I love this thing that much.
