I damn DIDDY you hit the nail!! Standard stuff already on the market here and there that has been specialozed for a particulaer market. A damn small market, as it has turned out.
A scam?? HAIL YES< a SCAM.. nothing revolutionary about it.
Much like we used to take a truck, put on a removable school bus body.. and use it during the summer as a regular truck, during the winter as a school bus..
BACK THEN, school ran from mid SEP to mid march.
