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 Monica Reese

After a few photoshoots it has become my backup trigger in case the others fail or the batteries die. One of the receivers often failed. I think the problem is with the cable connection. And since this set doesn't support high sync speeds, you have to be careful when increasing the shutter speed. I still use it and always carry it with me. I would add that this one is relatively easier to understand compared to more advanced sets: just turn it on and plug it in; others with remote control, you need to learn how to use it, of course I use the remote control as it saves me time :) Generally working but not reliable. And the trigger itself: I always worry about the battery going dead as there is no indicator, it's very difficult to replace (it doesn't use AA or AAA batteries and you need a tool to open the lid open to change the battery). That's why I get nightmares sometimes.
