I've been avoiding public eateries like the plague, so this is right on time to cure my starbucks fix.  4 options: cold foam, thick hot foam, light warm foam, and liquid warming.   I use the last 2 options as thick foam is too much.   Even with the light foam you get thick enough foam for cappuccino status, whereas I thought it would be more latte-ish.  I've been adding different flavors before brewing and the flavors are definitely intensified and infused throughout, giving a coffee house quality.  Worth the purchase if you're trying to save on daily coffee expenses.
