Product is advertised as having the viewers included. Too bad that the viewers are only an illusion. Don't be like me and order this DVD solely for the Illusion-O effect. The other problem with this DVD is that the "A" side is supposed to be the Illusion-O presented side with the "B" side being the non-Illusion-O side. Wrong! It's flip-flopped. Must have been burned wrong at the company.
