If the guarantee is short then I feel the manufacturer eithe
Zanussi Washcrafts didn;t have 10 year guarantees.
AEG Lavamats didn't have 10 year guarantees
Miele only offered 1 year guarantees until the early 2000.s
Bosch machines only come with a 2 year guarantee.
By your theory, this must mean that they are therefore of low quality too.
(Incidentally, my Maytasko only has a 2 year warranty, I must be imagining the quality of that too...)
I presume you have never seen let alone used a V-Zug, whereas Mike owns one - like the saying goes, don't judge a book by it's cover. It's a hard lesson to learn (lord don't I know).
Just a friendly piece of advice, nothing more nothing less...
