When I got to jam spoon WMF saw the first time I was done, this has unfortunately reversed reversed after the first use, because the usability of Einhängefunktion is not absolute given. Even the simple lifting or moving of the glass, the spoon adopted from that glass due to lack of maintenance. Accordingly, each morning, "Hand me the strawberry jam" is not without possible thereafter to have a mess on the table.
The only positive in this misconstruction of jam spoons is that it looks nice and is long enough to be used normally can without the ridiculous and nonfunctional Einhängefunktion. From this perspective, there are also some other, much cheaper spoon, which I eingehends advise against the purchase of this spoon.
