I would agree that DJI is cornering the market, but DJI is really messing with NFZ's for us in Michigan. We are flying 9 dji products at work and are getting NFZ's in areas that are Class G airspace below 700ft within 5 miles of some airports. The NFZ's along with the firmware and constant DJI Go4 updates, its really annoying my pilots to the point that they are looking at other drone manufactures like Autel and the Evo. They love DJI hardware, but have come to HATE DJI software and apps, to the point they dont trust it.
We will probably get an EVO just for yukes to try it out, as everyone is impressed when my Pumpkin saves the day because of a DJI NFZ or firmware update that grounds them. We fly Mavic Airs, Sparks, P4P, and Inspires.
If Drone Deploy, Pix4D, PrecisionMapper, all get on board and support the EVO for post processing like they do DJI products, it may sell a few, if they ever get it to market.
