Ebay doesnt sell anything that is a miscommunication between the buyer and 3dr. You bought it via ebay not from ebay.This is the e-mail I got from 3DR
"Hello,
Thank you for contacting 3DR Customer Support.
We are very sorry, but eBay is not an authorized reseller for the 3DR products and the warranty will not be valid through us.
Here is a list for the authorized resellers:
Solo Authorized Resellers | 3DR | Drone & UAV Technology
If there is anything else we can assist you with, please let us know. Thank you.

If 3DR honored a warranty on a product purchased on eBay, it's because they didn't know you bought it on eBay. Or they made a mistake.
