Unreliability (Nikon D750 hot shoe alignment issue)
The Cactus V6 II is unreliable.
1. TTL pass through - using a Nikon 750 and SB910, sometimes the flash works, sometimes it does't.
2. Triggering wirelessly - sometimes, the only way for the transceiver to update the power settings on the remote flash is to test fire the transceiver - this then updates the remote flash's settings but seems a waste of power and is inefficient. Other times, the remote happily updates the power settings without having to 'test-fire'.
3. It is weird that it can't auto detect my Nikon camera and Nikon Flash - ok once I have set the camera and flash to Nikon.
4. I cannot update the firmware (see separate discussion).
This isn't a cheap system but my experience so far suggests I paid too much.

I think the first 3 points are related to the hot shoe alignment problem on the camera model. As Fstoppers' article suggested, you need to extend the distance. Try sticking a small piece of masking tape and see if the V6 II can auto-detect your camera.
On the firmware I have replied you. There are no new firmwares released since V6 II launched.
And in your case, it's not a problem with V6 II, but the rather special hot shoe on the Nikon D750.
Thank you!
