Best frother I know

I had previously a Nespresso milk frother. This could be much more difficult to clean despite Teflon coating. He has even foamed milk for a cup and given no signal when finished.
The pot of Severin you can make if necessary in the dishwasher, but is not necessary.
Severin drawbacks: relatively loud, the lid tends to rattle and has after a year a lot of fine cracks.
