I splurged and got the new DJI Racing Edition goggles. I'm not into all the custom stuff yet.
They work great so far, but not able to use them alone without phone and just controller as I had hoped. Still have to connect your phone/tablet to the controller first in order for it determine where you are, unlock the height and distance limits, then turn on the goggles to use. A bit of a pain, but seems to be much less drain on the phone battery.
