To tell you the truth I'm fairly disappointed. I am not sure if it's because I was at a high attitude or the fact I still need to do the + vision mod but I wasn't impressed and it also seemed to really limit my distance. I didn't think it would make a difference on distance since it seems to just transfer the image to the goggles. On a flight route that I can get 4-6000 feet I was having issues at 2000 feet with weak signal and latency. Lastly I just got a windsurfer and that boosted that range from 4-6k feet out to 10k feet with unmodded system. With that being said the goggles still gave me that very short Range. Maybe once I get the vision mod I will feel different .
