Does anybody have any experience with the Proses BS-O-02 Ballast Spreader

The YouTube video of it in action is impressive. Their website says: "Yes this is for the laziest railroader". I still have a lot of unballasted track on my Poggenbahn layout and I suspect this is just what I need to get it over with. I'd like to hear if anyone else has used it.

Thanks in advance.
