Review on Wireless Flash Speedlite with Radio Slave for Canon - YONGNUO YN685 - GN60 2.4G System with ETTL and HSS Capabilities by Minoru Taguchi ᠌

I use a Canon 430 ex ii and an old Nissin puff. All flashes work in manual mode through YN622C. I brought home the YN685 flash, turned on with a pleasant sound, set all the parameters. The first puff is successful, then it does not work. Neither through a radio channel, nor directly from the shoe on the camera, nor with a synchronizer connected to the puff. The light for the presence of pairing via the radio channel is on. When you turn it off and on again, the puff puffs again (both from the shoe and through the synchronizer and through the radio channel), but only one. Then silence again. But if, after switching on, you do not remotely start the puff, but turn it on with a test button on the case, it works without restrictions in all modes. I'm going to change it tomorrow.
