I am on my 3rd. drone repair shop trying to fix my drone. I sent it to drone nerds.....partial repair. They said it was in mint condition but when I got it back the app lit up like a Christmas tree with errors. They keep it a month. Then I sent it to New York, expert drones. They keep it a month and did nothing to it and charged me 149.00!!!! Now it's in California at dronefly . I will say that they are the only ones who have stayed in contact with me with updates but I'm working on the 3rd week with them. This has cost me....I hate to admit this...but 500.00 and I still don't have my drone back. If I could work on drones in a timely fashion with good customer service, I could make a mint because so far I haven't had that and I'm at there mercy......just venting
