The series II Rogers was their worst marketing fiasco in the entire history of the company. The original designs were good enough, and if properly implemented, could have produced an entry level kit for an affordable price that would have been highly competitive with the import market. However, that was not the case. Cost cutting production measures, and an impractical use of plastic parts in construction of the drums, produced a line so filled with fatal flaws that within days of a sets sale, they were being returned to the stores. It took no time at all for dealers to begin refusing acceptance of orders and the company was left with a huge loss due to product failure.
