Review on 📸 Godox TT600 Flash Speedlite Master Slave Off GN60 | Built-in 2.4G Wireless X System Transmission | Compatible with Canon, Nikon, Pentax, Olympus, Fuji & Other DSLR Cameras | Standard Hotshoe Support by Cameron Kennedy

I use a lot of Godox strobes in real estate and architectural photography and for the most part I'm very happy with their performance. I have two GODOX TT600 flashbulbs that are of very little use; This will turn on and interact with the GODOX XProS trigger like day one, but will not fire. The back screen lights up, the Flash TEST button lights up, but when you press TEST nothing happens. I have sent several emails to GODOX to see if there is anything I could do on my end but received no response after they stated that they were very quick to respond to service/support questions on their site. ?
