Anyone know if this is an authorized DJI seller for the warranty to be valid?  I got two brand new units from them.

There are scores of people selling DJI products claiming to be "Official DJI dealers",
I recently had an experience with one of them. I bought a brand new P4P+ which arrived in a factory sealed box. Inside the remote was broken. I contacted DJI about warranty replacement of it. They told me that since I bought it from a 'Third Party Dealer' I had to deal with them. The seller didn't want to take it back, but thanks to the ebay buyer protection plan, they had no choice. I returned it for full refund.
There were no marks on the box anywhere. It was obvious that it went into the box damaged. I felt a bit sorry for that seller, because it wasn't their fault that it was broken, but it wasn't mine either and I wasn't about to be stuck with a broken unit.
You have to really watch out where you buy from. Unless it is such a good deal that you don't care about wether or not there is a warranty enforceable on it.

thanks. I wound up winning two bids on P3S, thinking at least one if not both would be outbid. So I wound up with two brand new units just lacking the outer box. Both are brand new in the box, and registered and flew successfully. I sold one to a good friend, but now am concerned he has no warranty if future issues occur.
