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

I have 4 pieces, I use them at a banquet. The first time I ruined almost the entire banquet, because these flash miracles were randomly cut down. I had to wander among them all over the hall, shoot from 3-meter racks and turn it on and off, then it started working again. After that, I wrote to the Chinese of the site and asked for the firmware, because this is the only method that could help me. But it did not help. For example, we shoot 20 frames by 21, one of the flashes stops puffing, and so on in a circle. And they all have such garbage. They were all purchased from different places. And it's not about batteries or settings. Even on the camera in the corner without sync, after 40 minutes of operation, the flash stopped firing. Good thing it wasn't at the time of the exchange of rings. Sell ​​them to hell. Do not buy.
