I've read on some threads that the goglles dont fully work yet with the Phantom 4 series specifically the 4 pro, is there any updates on this one if its been fixed with a firmware update or its still an issue? Still contemplating if I should buy it. Thanks heaps for any feedback.

DJI Goggles supports Phantom 4 series.
If you don't know if it is worthy to buy, you can experience it in local store firstly if it is convenient for you.
Here is link to find the store in New Zealand: http://www.dji.com/where-to-buy

I have Phantom 4 Pro Plus and will update you the fly video by using DJI Goggles after i do the Mavic pro.

Btw, for flying DJI Goggles you need to hook up the HDMI into Phantom 4 Pro Plus as a external live view.
