Yongnuo RF 603 N3 and YN 560 III problem 2

UPDATE ! - I bought a RF603IIC transmitter that works. I have a canon 60D now. I think the ones that are in the video are fake they work together but they do not work with Yongnuo 560 III flash. They were purchased from . The seller’s suggestion that sold me the flash is to remove the connection cable between camera and RF603 :) , yet I am unable to send signal from RF-603 to flash
