Pixel KingPro Nk King Pro Wireless 1/8000s TTL Flash Trigger with 2 Receivers for Nikon

I ordered King and King Pro. Now I am using King Pro to control King X and King RX. One problem I faced is the output of my flash is only about 1/4 of the full power. I am suing Nikon D800 and SB910. I set to manual mode. I noticed the output of your King Pro is much lower than the actual SB910 power. It failed my stage pictures. I spend some time at home to find out why. I use Nikon flash control (set to 1/1) and King Pro (1/1). I found out the output of King Pro is only about1/4 of Nikon flash control.Here is what I found out:1. if I set King Pro transmitter On and then King X on and then set my SB910 on. It seems sending the full SB910 output.2. If I turn off King Pro or King X and then turn on them again, highly possible, the output of my flash at 1/1 manual mode is only about 1/4 of SB910 full power.3. If after step 1, by any chance I pressed test button (King X or King Pro), the output of my flash will lower to about 1/4 of full power.I upgraded my King Pro to V103Same thing happened in TTL mode. I compared the direct On Camera and with King Pro installed On Camera flash, the output is also much lower.It is very hard to know if King Pro is at full power or not and you don't have time to play with it.A lot of misfires were also monitored with a 30~50 feet distance during my stage photograpy .I hope company will have new firmware to address these issues.

Works with Yongnuo 568ex flash (for Nikon) only after a quick firmware upgrade (downloaded from Pixel website).Original Nikon flash worked out of the box.The king Pro trigger compatible with the former king recievers.Pretty good most of the time, there are some glitches...
