I have a pair of Ziess Optimizer Goggles. Used only 3 times. Work fine. I bought with my phantom vision. Now use my iPad with tv in my truck. Paid $780 will sell for $680.
Looks like these may be gone... But I'd sure like to know more about them. Does it work like the Epsons? Download the DJI app? Or do they receive a feed from a phone?
