Loved this flash for many years, but these flashes are no longer reliable and lose sync with the trigger. Likely due to radio interference from either wifi or cell signals. I have 3 of them and 2 triggers and they are essentially worthless for intended purpose now.

Very unreliable radio connection in settings with Wi-Fi interference; like everywhere other than a park. There is no fix. Problem is well documented on Canon user forum. It's a shame as the build quality and feature set is up to canon standards. It's just useless if you need reliable off camera flash.
