With the Philips Senseo Viva Café Duo HD6566 / 30 Rosé Koper you can easily adjust the amount and strength of your cup of coffee. You can adjust the strength by turning the pointer of the button to the icon with 1 or 2 beans. When you press the preparation button once, you make a standard sized Senseo coffee. By pressing this button twice in succession, you make a small cup of coffee. You can place cups of different sizes under the adjustable metal coffee spout. As soon as the indicator light comes on, it is time to descale the coffee machine. Handy, because you don't have to keep up with this yourself. The coffee machine switches off automatically after use.
