For cappuccino, the foam is a touch better than the standard nozzle.
We drink our coffee milk drinks like with different syrups, these dissolve at this nozzle not so nice in the milk - in the normal nozzle, it mixes very nicely so that assumes also the milk froth the taste of the syrup, here the largest part remains separately under the milk. Especially strong this is in the preparation of Latte Macchiato
One selling point was the ability to establish warm milk because of this process but unfortunately also hot water is required, the milk diluted unfortunately.
I do not know whether the nozzle would bring possibly more if you had an older device, so unfortunately it was quite a letdown, and 50 for a touch better cappuccino foam were not a good investment.
