No, not in my case. They said that the machine had to be checked first. I found that very strange. It was sent back unopened. I can't say whether it was a new version. I then bought an original packaged machine in DE. It costs similar to the one in Switzerland.

Yes - as far as can be seen, a new machine with a CH plug arrived in Feb. 2021. That worked tiptop.

yes - at least that's how it was for me (purchase in autumn 2020).
