People are mostly complaining about their software issues here. I have to agree - firmware development for Goggles RE & Ocusync has been sluggish and many of the listed OSD features don't work as promoted. It is kind of sad because this is actually quite nice combo but the half-baked software doesn't prevent me from flying and I still prefer my DJI setup over any analog video links or Connex Prosight which I used to own before.

Here is a couple of my flying videos to proof that this thing is actually quite nice if one doesn't use automatic chanel selection or doesn't need a full featured OSD. And latency is quite acceptable, too:

Here is my latest  FPV vido with Goggles RE & Ocusync Air Unit. They are still working well after 1,5 years and a couple hunded flights.
