Guys, im not going to debate the issue, il state the facts
You buy a drone then you buy a NLD license.
If you crash the drone, why would we give you another license for your new drone?
Out of courtesy, we give a 20% discount on a second NLD license if you crash your drone.
If your drone gets replacing using DJI's Warranty services, then we replace the NLD key because its not your fault that the drone broke.
The reason for this is very simple. You could be buying drones, modding them and selling them online, then come to us claiming the drone has been crashed, get your key reactivated, rinse and repeat.
We realise this may annoy some people, but we dont have any other fair way to do it.
