One year later:
I have now gained me a Hohner Marine Band Deluxe.
The difference from the Silver Star is clear.
The Silver Star has a thinner sound, and is much quieter.
The Marine Band Deluxe is easy to record, because the mouthpiece is flatter and the Tonkanzellen closer together - this could be an obstacle for beginners as well.
Conclusion:
For beginners, but once you get a little more advanced is no longer usable.
