+ The engine is really strong for this purpose. I often frothy milk for 3 large latte macchiato at the same time and for the Caso which is not an issue (if not the battery empty, of course). It is quick and the foam is super.
+ The included stand is very convenient. The foamer is tidy and not somewhere around.
- The stirring rod is perhaps a bit too thin. Mine is definitely still quite straight, but you should be careful that he does not bend. If you leave the unit to rough handling and fall to the floor every 2nd day but that should be no problem. Since my stir bar has not really bent, but is only, in my opinion, at risk, I pull it off and no star.
PS: My tip for good milk froth: H- or whole milk 3.5% fat, not too much heat. I give always in the milk sugar (coarse cane sugar - great flavor!). I have not had good experiences with organic milk for some reason. No idea why, but the varieties tested, I have no stable foam hammer out (?).
