Well, I can't find official website. Either this piano is a miscellaneous brand, there is no regular manufacturer, or it is a new product. I have no time to do it. No one used it and didn't know whether it was good or not, so there was no evaluation. My understanding is this. The landlord asked the sailor and this, but I don't really understand it. After reading it, I thought that sailors were German, and official website commented a lot. It should be better than that. Personally, I think it is.
