IMO, they aren't the bad guys here, any manufacturer aside from a few can easily change their product serialization, usually just a matter of changing a sticker. This drone is no different. If they were inclined to resell a used one as new you'd never know since they have access to all the parts to make it look new again. Sometimes we just have to trust the company you buy products from. I kinda understand where you're coming from though, seems like being dishonest in business and government is getting allot of attention these days.
