Review on 📸 Hot Shoe Sync Adapter for Canon Flash with Optical Flash Slave Trigger, PC Socket & Sensor (excluding 540EZ) by Antonio Taveras

I received this device and tested it at my home and it worked fine. The problem is I didn't buy this fixture for indoor use, I intended to use it outdoors for accent lighting. I can't bring myself to work outdoors during the day, even in shaded areas. I even tried holding the trigger flash directly in front of the sensor but it still didn't fire. Put it back indoors when the light is low and it works again. For this reason the device is almost unusable for me.
