Godox XT-16 Wireless Power-Control Flash Trigger 2.4G (Transmitter and Receiver)

This is the second XT16 trigger I have purchased in the hope of getting a more consistent response from my QS600II studio head kit. Unfortunately it hasn't made any difference, it appears the connectivity becomes broken very easily. Even when turning the trigger on and off and hitting set to show the output change to confirm it is talking to the light, this makes no difference to its responsiveness. I am not shooting rapidly so its not misfire and there is no pattern to when the heads respond. Using 2 heads, one fires and the other doesn't and vice versa so its not a particular studio head issue. I purchased a sync cord which is an improvement to consistency but doesn't solve the radio frequency response of trying to use the other light on slave as I still end up with misfire. Turning the units and trigger on and off constantly to reset connections is unacceptable. My previous kit from SLS brand fired 95% of the time using the wireless triggers, the godox triggers only fire 70% of the time which causes delays on every shoot I have used them for.
