Processing: It is nice that you can make the glass container on the stove (no cover) - at least Ceran. Annoying is that the lower end of the plunger is below the screen made of plastic. One stomps on the hot plate and forgets too long in a few seconds, that could probably anschmilzen in milk. Furthermore, small droplets splashing milk out while pounding. Not much, but every time you have laying around 3-5 drops of milk - on the stove burn at once and it smells.
Foam: Contrary to other reviews I have to say that the foam is great and in 10-20 seconds the foam fills the tank to 50%. But there remain about 10% (ie absolute 20%) under the milk foam. This is not a criticism, since one needed not only foam in a latte.
I have 17, - Euro paid. He is fine, but not worth the price. For 10, - recommended.
