I have to say.... First of all I cannot comment on the horizon issue as I'm not that Savy about it.
What I will say and maybe I came a little late into the drone world. I have flown RC Heli's and have seen them evolve over time.
I'm speechless with the technology and implementation of technology that DJI has done to come up with the Phantoms and Mavic. Not only that, but I have used DJI GO4 app since I started flying the MP and I was on Firmware.05. I'm still impressed with what they have done. My first impression was the packaging, then holding mavic for first time and then first flight and to this date ever so happy.
It may not be perfect, but **** they have done great so far in my eyes. I Hear so any people complaining about DJI yet they still keep using their products.
I just recently rolled back to 04 because I wanted to try out Litchi. But if Litchi or Some of the other apps were not around I'd still be happy. I've been able to make some family videos, nature recordings and other recordings using the MP so far with no other app than DJI GO4.
So I'm going to give them lots of credit here and say.... Your doing great, keep up the good work and bring us more functions on the app and more drones. Can't wait to see what's next.
