The only tiny gripe would be possibly that the Metallschäumer is firmly mounted on the handle, so you can not take it off for cleaning. Especially, if you let the frothers are a little moment, that's too bad.
And secondly, that you can not stand him.
Personally, I can see over it and Bypass Both, as I always abspühle him immediately after foaming under cold water and rest it on my kitchen shelf on the wall.
On the whole, one gets the Scanpart for this handleable price but a really good and powerful device that diligently doing his job. Therefore, I full 5 stars.
