worth the change from 520 to 550?

After almost 4 years Lattissima EN 520 has passed away in our household.
In this context, but you have to also mention that the machine has been very heavily used. It was good
Product is shown by the fact that this product is still available today.
We have long wondered whether we the old model or this machine, which should 550, choose.
The specter of the ban on non-compatible capsules was about.
Suffice it to say the same: the Lidl, capsules, the pink of the net and the Dallmayr-capsules "eats" the 550 without complaint.
Also one can not say anything negative, because the 550 is practically just as good that the still available Nespresso machine EN 520th
This has proven itself over the years up to this day, a second copy of the house is still in use

The operation of old to new model is virtually identical. Similarly, the cleaning function of the milk apparatus.
Key differentiator are the two extra buttons on the top of practically two other "specialties" so mixing ratios milk / coffee offering.
Whether one likes it currently spend about 100 euros more, everyone must decide for himself.
Top machines are both, with the model 550 first must make the long-term practicality test.
