I have this machine for almost two years. First point is rather beautiful but somewhat cumbersome, focus placed near a wall the water tank is difficult to remove. Very effective tactile buttons with easy cleaning. From my side I do not see any difference with the Bryta system so I stopped ordering spare filter cartridges.
Very positive point: reliability, my experience (I drink coffee MUCH, at least 5 per day) this is the first Senseo machine that takes the shock as well (lots of failures with other seines in the past).
