New models of Petra is not necessarily better

Positives:
+ The design is indeed a matter of taste, but clearly modern
+ Insert Pad works with minimal pressing the pads always and without effort
+ Machine drips as opposed to KM 31.17 not so long after
+ "Program selection": from espresso to Jumbo cup you can always find the right capacity
+ Lock makes to be more stable and is easier to use than the old slide
+ Water filling side (easier for me to benutzenn as the complete removal of the tank, because over the Petra hangs a wall unit)

Negatives:
- Kaffeauslass is high but not height-adjustable, so that theoretically espresso cups can indeed be filled, you have to keep this up but,
so not everything is covered with sperm
- Crema was yesterday! At least with my model is at the same pads that Crema clearly coarser pores than the KM31 and KM 42.17, and falls more quickly together
- Probably an isolated case but annoying: after just 3 weeks use the handle of the pod holder loosely because the outside is not zugänliche fixing
is terminated on one side. Occurred after the problem is cleaning of the holder in the dishwasher
- At the same pads and the same amount of water the coffee tastes a little thinner

My conclusion is made by growing.
On the one hand, I like the new look of KM 39.07, and increased usability on the other hand was the coffee of 31.17 KM clearly better.

Addendum:
After the manufacturer had quickly sent a replacement part for the broken pad holder,
joined the same problem (bröselnde Aperture) also the new part.
Obviously, contrary to the indication of the operating instructions, the dishwasher suitability of all
moving parts not given. Used by me getting a 50 ° wash cycle.
