I am looking on Gumtree at the moment and the average price for a used
Phantom 4 pro is about 2000 Australian dollars some in excellent condition with lots of extras and batteries up to 2800. That seems pretty reasonable to me I paid in all about $3,000 with lots of batteries and two charges props so to get about 2,000 I would be happy with that. That's the world I live in anyway I don't know where this 400-500 thing came from.
I also don't live in a world where you sell something and then a few months later sell something better cheaper and it's ok.
But each to their own reality.
DJI have apologize profusely to me and I've been negotiating with a very nice chap but he can't do anything because DJI I don't want to because I think they're dodgy on this issue. Yes very shady and shoddy.
I truly believe DJI can be better than that.
