Review on 📷 Altura Photo Wireless Flash Trigger for Canon - 2 Pack with Remote Shutter for Canon EOS 80D, 77D, 70D, 60D, Rebel T7i, T6i, T6, T5i, T5, T4i, T3i, T3, SL1, SL2 DSLR Cameras by Eric Dailey

After I installed four small switches in all devices and inserted batteries, I was ready to go. It takes a certain amount of skill to manually adjust your camera and flash settings for proper exposure. And you have to set the flash strength on the flash, not on the camera or with triggers. I get multiple flashes in a row without crashing. If you plan to use a trigger mounted between your flash and a tripod or umbrella/flashlight stand mount, be careful as the lower base appears to be a lightweight construction. Unsurpassed quality! For about $100 I bought 3 complete sets. I can fire four flashes at the same time, hold down the camera shutter button on either camera and simply take the chosen camera/lens for a shot (head or full length). That still leaves me with a full spare set (I drop things that aren't attached with a strap). Free bonus. If you want to remotely press your camera's shutter button, that will do as well.
