With the Philips Senseo Viva Café Duo HD6566 / 30 Rosé Copper you can easily adjust the amount and strength of your cup of coffee. You adjust the strength by turning the knob's pointer to the icon with 1 or 2 beans. When you press the cooking button once, you set a standard size Senseo coffee. By pressing this button twice in succession, you put a small, strong cup of coffee. Under the adjustable metal coffee spout you put cups of different sizes. As soon as the indicator light comes on, it is time to descale the coffee machine. Handy, because you do not have to keep up with this yourself. After use, the coffee machine switches off automatically.
