Manufacturer/Distributor/Vendor and Customer Disputes
This forum is not intended to be a mechanism for people to vent frustrations about manufacturers, distributors or sales from private parties. Please settle your differences with the seller, manufacturer and distributors through other means but not through our community.
So as you can see this applies to any & all vendors, not just DJI. I personally will leave post that are useful but typically a hate thread has no useful info. So if you see a thread get deleted or post being removed you can rest assured that is provided no useful information.
