When I looked at the manual, I almost passed out with laughter. Everything is very detailed explained in Japanese / Chinesich and is explained in very bad English. Since the remote control does not have too many functions, one has to over 10 minutes away, even without instructions all explored. The workmanship is good and the remote fits comfortably in your hand. It is possible aufzustecken the receiver on the connection for the flash. With a cable, the receiver is connected to the camera. The range is very good. The exact distance I can not judge, but through two closed rooms, the camera fires still.
