DJI service, plain and simple. And the way dji has had prices up and down. I think, and this is just what I think, they should be a stand up company, and be loyal to the people that buy their products, and take care of them if they have a problem. They haven't done that. In most cases, if you have a problem, you're on your own. And if they do decide to look at your drone, whether they fix it for free, or charge you, you say goodbye to the drone for 6-8 weeks, minimum. I wish I had gotten on this site long before I bought one instead of in desperation after I took delivery, and couldn't get the firmware to load for 2 weeks. That's why.
