We can use it to make good espresso, which is however also the good coffee beans. However, she started after two weeks to make strange noises and eventually also produced shortly thereafter no more steam.
After such a short time, it may not have been due to hydraulic lime. In addition, we used a water filter.
Our guess is that the internal pump is poorly designed.
I can not recommend this machine unfortunately. This is the time in which this has to work, too short.
