The replica really looks exactly like the original Canon ASU only just forward it stand "for Canon" :-) But at the price you can not complain there really. Works flawlessly. If you (as seen from the lens front) from the front right ziehlt on the camera so does the trigger still loose from 5m Entferndung - because the infrared sensor on the side of the lens.
Conclusion: OK for your price. (I probably had luck with the delivery. My mission was there for two days.
