Review on ⚡️ High-Performance 16-Channel Wireless Radio Flash Speedlite Studio Trigger Set with (1) Transmitter and (4) Receivers, Compatible with Canon, Nikon, Pentax, Olympus, and Panasonic DSLR Cameras - CT-16 by Brad Cao

I have used these few shots and am very happy with them. While they don't appear to support rapid fire, they're easy to assemble, easy to sync, and have worked flawlessly so far. Great deal for the money. However, if you need fast/stroboscopic firing (multiple flashes per trigger), high-speed sync, rear-curtain sync, multiple trigger groups, or remote flash output, you need a more expensive branded product. This is the basic remote control for studio and flash units. Each receiver controls only one flash. The trigger only controls a synchronized set of receivers (as many as you have set on the specified channel out of 16 possible channels).
