I just received my Phantom 3 Professional that I ordered from Adorama on Black Friday. Upon opening the box, everything seems fine. Except... The outer box is dirty(Probably from storage). So I thought 'Okay. That doesn't mean anything'. And I opens the box. Start charging the controller. After 3 hours, I decide to take a look and see if it is fully charged, then I can move on to charge the battery. Then I noticed..... Old Motors, and old shell. And for some strange reason, the motors doesn't have the 'safety sticker' on them. And I realized this is probably a returned unit.The accessory and charger box have clear evidence it had been opened, and put back together. Now I have packed everything packed back exactly the way it arrived. Now, should I return it, and ask for a replacement? The opened box doesn't really bother me, as the phantom still looks like it had never been flown. But I have heard that old motors causes cracks. And Adorama basically gives no support similar to DJI except for the first 30 days. I don't want to wait the the cracks appears, and then I would have to send it in (to China) for replacement, and probably pays a huge repair cost. And Adorama's return policy is kind of worrying. According to their return policy, they will deduct the original shipping fee. Is the motors really a huge deals and worth my effort? How do I make sure so the replacement will have the new motors, and not a returned unit? Thanks everyone.
