I have another good Senseo + old, well used + (lot actually), and it works perfectly. It was a little + expensive to buy ... but impeccably works!
Would they be of lower quality parts assembled on the top prizes Senseo ??? My mind is made up anyway!
Or maybe it's the fault of bad luck. Everyone around me little change them after two years of use, thus providing 60-70 coffeemaker approximately every 2 years for his coffee.
Otherwise, the coffee is very good, a little too "filters" to my personal taste (and my wife love it by cons), a little too much water, not tight enough. To compensate, I remove the very beginning and especially the end of the coffee spout to make it better.
