I must say in advance that I had the opportunities, and partly still have to test the three pad machines with milk foam apparatus. The Senseo Latte Select is at my parents the household Petra I have owned for a short time and now I have the WMF 10. First to the Petra KM45. In short I had bad luck. My machine has produced from the outset no milk foam and so I returned the machine and bought the WMF10. Why did I then placed the Petra 4 stars? The coffee was fantastic, the included accessories is great and the service and choice of drinks is unique. If my machine would have worked, we probably would have become good friends. What it is to be observed in distinguishing the three devices, which is the Petra and the WMF of the construction are the same !!! Whether it is the water tank (because you probably could even replace), the milk foam unit, the pad cassette and even the text in the manual is part way to 100% compliant. Can you justify the fact that the Frima Petra has been acquired by some time by WMF and therefore we have two devices in almost the same electronics! So compared to the 3Maschinen I would Petra highest rate for the following reasons: 1.Toller coffee taste (but is probably related to the pressure on the pads together / is the same for the WMF) 2. easy to use thanks to the rotary switch 3rd and of course the price 4. Who says now: Yes, yes may be already but WMF is ne completely different brand. As I said, the Petra and the MWF differ only in style. Therefore, very strong buy recommendation for Petra and although I was unlucky and have decided otherwise.
