Defective and returned. I have proof of this being returned and Revain has confirmed it and they will not give me a refund! I'm now without a drone for work, I can't buy a new one because Revain won't return the money. You have to fix it. We used it lousy twice before it broke the picture and the video quality was great. Our customers were completely satisfied. It cost us business because of a malfunction. Revain does not help to solve this problem. Be careful when buying this as they change their return policy every day I've spoken to them!
