Although it is not yet free of teething troubles but the interaction with the app works almost always very good. A systematic crash with me unfortunately was under "instructions, descaling" so far no indication of the cause, especially since all the other functions work exemplary. The crema coffee or milk could be better ie fluffy. This create other machines a little better. The simultaneous attachment of two latte macchiato glasses is not possible, as well as the use of larger glasses. The constant flushing function limits the functionality slightly. The queue function is good and very easy to use. The machine makes a robust and high quality impression. The purchase price is quite high and everyone must decide for themselves whether it is justified.
