Tried this with a full pot of milk and then with a smaller amount. For both, yes it did froth brilliantly but not only was it cold, it spilled out of the lid. If you use the tiniest amount of milk it probably would work but going to the suggested minimum did nothing to help the overspill which came leaking out of the lid.
Froths and heats milk quickly to make perfect lattes, cappuccino etc. Jug holds enough milk for two or three drinks so very energy efficient. Easy to clean and looks good. Highly recommended.
