When I first saw this technology demonstrated in China I thought that it would not be long before it became available to the rest of the world. Today I picked up a YouTube video demonstrating the device with a link to a DJI shop in Madrid so I went ahead and purchased it for my Mini 4 Pro along with the necessary adapter. I have always been interested in anything that can improve the connection between the remote and the drone as I often fly from my garden which has lots of trees around it. I am sure that it will eventually replace OcuSync in DJI drones in the near future. For anyone interested I have included a link to the Spanish YouTube video which has English subtitles.
