Operation is naturally somewhat complicated by the increased features than the Senseo Quadrante, but not difficult. Instead inserts the Petra also has a drawer for pads, with two sides (normal pad, dual pad or coffee filter).
Unfortunately, Petra also has some pitfalls. So the rear suspension of the water tanks is something hakelig and me it's already happened here is that suddenly shot out a splash of water. Unfortunately, he can not simply be put down outside the unit, where he gets up on shaky ground.
Something similar happens when you can not even about 0.5cm further behind pushes the coffee icon the slider for setting the function (enable Padschublade, hot water, and coffee creamer) and suddenly all the sauce is pressed out to the drawer. Well, happens once, then you know it. Annoying it is still and guests are inclined to make the same mistake.
Otherwise you can be really satisfied with the device. The Petra heated similar to fast as the Senseo (I've heard the rumor that this would allegedly take many times - but it is just a rumor) and the coffee tastes - for whatever reason, a real declaration does not like me so really think of - felt with the same amount of water Padsorte and stronger and not so thin.
Conclusion: Because of the diverse possibilities and the favorable price, I would prefer a Senseo Petra again, albeit slightly. The above-described problems with unwanted water loss press something on the result, but are to get a grip and then no longer occur during operation.
Best to use instead of the low water line at the discount: Here's a tip to those in regions with a high degree of hardness. Then, the machine must be descaled less often.
